EHSAL – Zvýšenie uskladňovacej schopnosti vodíka v ľahkých vysoko-entropických zliatinách (HEA) typu AlTiVCr prídavkom Ti3C2 Mxenu a veľkej plastickej deformácie
Enhancement of Hydrogen Storage Properties of AlTiVCr Light Weight High Entropy Alloys (HEA) by Ti3C2 Mxene and Several Plastic Deformation
Program: European Interest Group (EIG) CONCERT-Japan
Project leader: doc. Ing. Saksl Karel, DrSc.
Annotation: Recently discovered AlTiVCr high entropy alloy (HEA) exhibits about 70x increase in equilibrium pressure, ~20 kJ/mol H2 decrease in desorption enthalpy (ΔH) relative to the benchmark TiVZrNbHf HEA possessing H/M ratio > 2 with 2.7 wt % hydrogens at 53 bar H2. The AlTiVCr HEA desorption enthalpy ΔH is ~40 kJ/mol and H/M ratio ~1. Since AlTiVCr alloy includes lighter-weight elements relative to earlier studied refractory HEAs, it is envisaged that AlTiVCr can be a potential lightweight metal hydride for future hydrogen storage application if its H/m ratio and hydrogenation/dehydrogenation kinetics can be improved. So far, the addition of Mxene (Ti3C2) as catalyst and nanosizing exhibited a significant influence on the kinetics and hydrogenation capacity of Mg metal hydrides independently. Therefore, in this study, we aim to develop a lightweight metal hydride composite of AlTiVCr HEA by the combination of three concepts of HEA, Mxenes (Ti3C2 Mxene) and nanosizing by high-pressure torsion (HPT). The influence of Mxene and deformation heterogeneities will be investigated and will be tailored for achieving lower ΔH, higher H/M ratio and faster kinetics.

Príprava a charakterizácia pokročilých anorganicko-organických polymérnych hybridov pre 3D tlač
Syntesis and characterization of novel organic-inorganic polymeric hybrids for 3D printing
Program: Inter-academic agreement
Project leader: Ing. Bureš Radovan, CSc.
Annotation: Three-dimensional printing is currently largely bound to the use of polymer materials supplied bythe printer manufacturer. This, however, greatly limits the wider application of 3D printing of objects with specific physicochemical and mechanical properties. The primary reason of this limitation is the requirement for biocompatibility, biodegradability, enhancement of anti-corrosion properties, or specific requirements for the mechanical and electrical properties of the resulting products. Consequently, the objective of this project is the synthesis and characterization of novel advancedpolymer composites with inorganic fillers applicable in 3D printing. The aim will be to examine the influence of the size and shape distribution of inorganic fillers on thestructure and physicochemical properties of the newly formulated composites. Increased attentionwill be paid to modifying the macromolecular structure and microstructure at the interface between the organic and inorganic phases and unveiling the induced changes in the macroscopic properties of the infiltrated hybrid materials.

Progresívne metódy úpravy funkčných a mechanických vlastností práškových materiálov
Progressisve methods for treatment of the functional and mechanical properties of powder materials
Program: Inter-academic agreement
Project leader: RNDr. Kovaľ Vladimír, DrSc.
Annotation: Rapidly solidified powder alloys as well as mechanically prepared powder metal alloys have a limited plastic deformation capability. Limited plasticity of the powders leads to their limited form-ability and in some cases prevents compacting of the powder by uniaxial cold pressing. Structural defects typical for mechanically synthesized alloys also cause deterioration of their electrical and magnetic properties. The aim of the project is to investigate the progressive processing methods of mechanically prepared powder alloys in order to improve their compaction, while maintaining or improving their electrical, magnetic and mechanical properties. The project solution can bring original findings, leading to expansion of the usability of fast-solidified and mechanically synthesized alloy powder materials in industry.

Development of novel multifunctional materials for next generation magnetoelectric sensors and data storage devices
Program: Bilateral – other
Project leader: RNDr. Kovaľ Vladimír, DrSc.
Annotation: The main goal of the proposed project is to establish and develop a scientific cooperationbetween Slovakia and China in the field of multifunctional materials for advanced applications inmicroelectronics and spintronics. Joining of the research teams from both countries is motivatednot only because of great technological potential of multifunctional materials but also due to thefascinating physics behind their unique properties. Multiferroics, exhibiting simultaneouslyferroelectric and magnetic properties, are among the most attractive multifunctional materials.They allow for controlling the magnetic state of multifunctional devices with an external electric field, and vice versa. The main obstacle is, however, the scarcity of multifunctionalmagnetoelectrics in nature. Currently, single-phase multiferroics are far beyond any practicalapplication, because they only demonstrate useful properties at very low temperatures.Recently, we showed that Aurivillius-type ferroelectrics doped by magnetic atoms can exhibitmultiferroic behavior at room temperature. The origin of magnetism and magnetoelectriccoupling in these materials, however, still needs a proper interpretation and confirmation fromdetailed experimental and theoretical studies. Our aim is to combine research on multiferroicmaterials in Slovakia with activities in China on theoretical modelling of multiferroics to designand prepare single-phase materials with the improved magnetoelectric property at roomtemperature.

To obtain materials with a broad range of physicochemical properties the polymer matrix, for instance polyurethane based on polybutadiene blocks, will be modified by different types and amounts of metallic nano-particles. Indispensable part of the proposed project is detailed structural and physicochemical characterization of the prepared composite systems. For such task specific correlations between mechanical and electrical properties and the chemical composition of the prepared systems will be primarily studied. Molecular structure will be probed by FTIR and ssNMR techniques while surface morphology will be determined using advanced microscopy. Successful solution of the proposed project requires extensive knowledge transfer between both working groups.

MAMINA – Makro, Mikro a nano aspekty obrábania
Macro, Micro and Nano Aspects of Machining
Program: FP7
Project leader: doc. Ing. Saksl Karel, DrSc.
Annotation: The use of titanium, nickel-base and cobalt-base alloys is necessary for production of turbine parts and other components by the aerospace and power generation industries due to their high strength even in high-temperature regimes. On the other hand, these materials are known as themost difficult-to-machine metallic materials and, so far, only small progress has been made to improve their machinability. During the production of turbine components up to 50% of themanufacturing costs can be related to machining. Hence, the reduction of the production costs bythe optimisation of the cutting process is mandatory for European manufacturers to remaininternationally competitive.The MAMINA project will combine the work of ninenteen European universities, researchinstitutions and industrial companies to analyse and improve the machinability of three selectedalloys that are widely used in industry, namely Ti15V3Cr3Al3Sn (a titanium-base beta-alloy),Inconel IN706 (a nickel-base superalloy) and X40 (a cobalt-base alloy). As the chip formation isone of the key factors influencing the machinability of these materials, this process will be studiedin detail in a multidisciplinary approach. 24 early stage researchers from the fields of theoreticalphysics, materials science and mechanical engineering will work under the supervision ofexperienced scientists on metal cutting experiments, material analyses and simulations at the macro,micro- and nano-scale.Three different approaches will be made to improve the cutting process of the investigated alloysby means of: (1) introduction of enhanced manufacturing techniques; (2) production of progressivetools with extended endurance, and (3) development of free-machining alloys by the use ofpermanent and temporary alloying elements.

INNOVATTOOLS – Inovatívne prístupy k zvyšovaniu životnosti a znižovaniu energetickej náročnosti rezných nástrojov pri spracovaní dreva v lesníctve
Innovative approaches to increase the lifetime and reduce the energy consumption of cutting tools in wood processing in forestry
Program: SRDA
Project leader: RNDr. Džupon Miroslav, PhD.
Annotation: The project will address the issue of the use of methods and procedures for the modification of cutting tools for wood processing in forestry. The result will be an increase in their lifetime and a reduction in emissions and energy consumption of forestry machinery and equipment. The main objects of research will be tools for primary wood processing, modification and processing of forestry biomass for energy purposes, such as splitting and chipping tools, tools for cross-cutting wood, etc. The main task of the project will be the design of procedures and methods for the modification of exposed functional surfaces of the tools. Ensuring a higher quality of functional tool surfaces in the context of reducing friction and eliminating adhesion, provides a prerequisite for reducing the load on machinery equipment and thus reducing emissions and energy consumption in a given production. Analyses will be carried out on the tools – FEM analysis in order to determine the stress-strain state, on the samples analysis of the state of the material in terms of physical properties, microstructure, mechanical properties and resistance to adhesive wear in wood-metal interaction and also abrasive wear. Based on the results of the analyses carried out, innovative surface treatment procedures will be proposed for the exposed functional surfaces to guarantee an increase in their functional lifetime. These will be applied to samples and laboratory tested by relevant test procedures. From the results of the laboratory tests, a selection will be made of the most appropriate non-conventional innovative procedures, which will be applied to the tools and tested on the equipment under forestry operating conditions. In doing so, it will be observed how the modifications in question affect the energy consumption of forestry machinery and equipment. Part of the project solution will be to ensure industrial-legal protection of the original solutions.

Development of innovative methods of processing and joining electrical steels for high-efficiency applications in e-mobility
Program: SRDA
Project leader: Mgr. Petryshynets Ivan, PhD.
Annotation: The global trend to reduce emissions has forced car producers to think about other types of propulsion thaninternal combustion engines. A significant direction in which the world is currently moving in this area is thereplacement of internal combustion engines with electric car drives. This fact has led and it is still leading to a greatexpansion in the production of car batteries, which would allow the longest possible range of electric cars. Besidesthe capacity of the batteries, the efficient use of stored energy in electric vehicle drives has a significant effect onthe range of cars as well. This project aims to reduce losses and increase the efficiency of electric drives.Increased efficiency and reduced losses can be achieved by reducing the losses in the materials of the rotors andstators of rotating electrical machines, but also by reducing the losses that occur when changing the properties of the source material during cutting and subsequent joining into rotor and stator bundles. Experimental research will focus on optimizing the microstructure and texture of various grades of electrical sheets in order to minimize electromagnetic losses and optimize the conditions for the production of rotor and stator bundles by cutting and subsequent joining. The optimization of the conditions of joining electrical sheets of various chemical and microstructural concepts will be the expected output of the project. The magnetic properties of the joined electrical sheet cut-outs will be compared with the magnetic properties of the lamellas produced by electrospark cutting.

HERO – Elektrokatalyzátory pre efektívnu produkciu vodíka pre budúce elektrolyzéry a palivové články
Hydrogen evolution electrocatalysts for future electrolyser and fuel cells
Program: SRDA
Project leader: RNDr. Strečková Magdaléna, PhD.
Annotation: The development of activities in the field of hydrogen technologies was also supported by the EuropeanCommission in the strategic document "Hydrogen Strategy for a Climate Neutral Europe". Today, Slovakia hassuggested own national hydrogen strategy. Already in 2015, the National Hydrogen Association has founded tosupport research, implementation and use of hydrogen technologies. The Hydrogen Technology Center is beingestablished in Košice with the main "Power-to-Gas" concept using renewable power energy sources with nonegative impact on human life and without dependence on fossil fuels. A significant source of hydrogen is waterand the electrolysis of water is the most promising technology for hydrogen production. However, before it can berecognized as an economically significant resource for large scale application with an exceptional energy potential,the simple, efficient, and secure methods of hydrogen retrieval have to be developed. For the time being, the mostefficient electrocatalysts in terms of overpotential for hydrogen evolution reaction (HER) are noble metals.Unfortunately the high cost and scarcity of noble metals motivate the scientists to find the rival low-costalternatives. Intrinsic structures of TMP meet the criteria of outstanding electrocatalysts that could further improve their HER performance in membrane electrode assembly. Excellent dispersity of electrocatalysts allows full use ofactive sites on catalysts to participate in electrode reaction to improve the electrocatalytic efficiency. Therefore, themain challenge in this project is to reduce the production cost of HER and at the same time to maintain the highefficiency of polymer electrode water electrolysis. Substantial aim of the project will be devoted to improve the PEM water electrolysis components mainly electrode materials based on modified carbon fibers electrocatalysts result in the technology which should be more approached to commercial markets.

Hard and tough boride and nitride-based coatings prepared by advanced PVD techniques
Program: SRDA
Project leader: doc. RNDr. Lofaj František, DrSc.
Annotation: The project aims at the increase of fracture toughness of thin hard PVD boride- and nitride based coatings deposited using advance sputtering techniques including HiPPMS and HiTUS while keeping their high thermal and oxidation resistance by means of employment of the intrinsic and extrinsic factors. The main idea is based on a „new design“ of hard coatings including simultaneous contribution from the modification of chemical composition, morphology and structure of the coatings via exploitation of the potential of structure control provide by HiPPMS and HiTUS technologies with high level of sputtered material ionization and high density of working gas plasma, respectively. Both technologies result in the coatings with high densities and allow us to modify the nanostructures, size of the nanocrystallites, modify chemical composition etc. and subsequently, to obtain different physical properties of the coatings. The activities of the project are focused on the development of transition metals-based boride and nitride coatings with improved mechanical (hardness > 30 GPa) and tribological properties (coefficient of friction < 0.3) for extreme conditions (> 1000°C, aggressive oxidation environment, etc.). The main effort will be oriented toward the elimination of the main drawbacks of hard coatings, i.e. toward the increase of their inherently low fracture toughness and increase of their oxidation resistance without hampering their hardness via understanding of the mechanisms of nanostructure evolution, decomposition of the high entropy multicomponent solid solutions, formation of stable phases and their relationships to mechanical and tribological properties. The research activities include also the correlations of the experimental results with the ab initio predictions based on theoretical models related to atomic structure and electronic configuration of the studied systems.

PNMHCS – Výskum a vývoj prototypu nízkotlakovej čerpacej stanice pre zásobovanie metalhydridových zariadení zeleným vodíkom
Research and development of a prototype of a low-pressure refuelling station for refuelling metal hydride equipment with green hydrogen
Program: SRDA
Project leader: doc. Ing. Saksl Karel, DrSc.
Annotation: The purpose of the project is the research, development and designing of a prototype of a low-pressure refuelling station intended for refuelling mobile technical equipment for hydrogen storage at low pressure in metal hydrides (MH). The existing infrastructure for hydrogen production that applies a renewable energy source in water electrolysis will be used, while the green hydrogen generated in the process of electrolysis will be stored in stationary tanks with an absorption-based storage system. A strategic objective of the project is to interconnect the system for green hydrogen production operated in the island mode, installed at the Centre for Hydrogen Technologies at the Faculty of Mechanical Engineering, with a system for stationary low-pressure hydrogen storage in metal hydrides, which will then facilitate refuelling mobile MH equipment using a newly developed prototype of a refuelling stand. An important milestone in the project is the research into a design of stationary tanks with an inbuilt thermal management system. Developing the thermal management system is crucial for operational safety and for increasing the efficiency of hydrogen storage while considering the overall reduction of energy consumption in the process of hydrogen absorption and subsequent desorption. The research of novel MH alloys, while respecting equilibrium pressures at predefined operating temperatures, is therefore a primary input parameter for designing the thermal management system. The use of MH alloys for increasing hydrogen pressure eliminates the risks related to the compression process when compared to mechanical compression. The thermal management system will also include a system for cooling hydrogen during refuelling; hence, reduction of the time of refuelling MH tanks for consumers will be verified.

Program: VEGA
Project leader: doc. Ing. Saksl Karel, DrSc.
Annotation: The aim of this project is the development and research of high-entropy alloys – HEA whose primary function will be in hydrogen storage. Commercial use of H2 relies on its efficient and safe storage. One of the most efficient ways to store H2 is chemically bond it to an alloy lattice in a form of metalhydrides. The TiVZrNbHf alloy is capable of storing far greater amounts of H2 up to 210 kg.m-3. The problem of the alloy is its relatively high density of 7.81 g.cm-3, for transport applications. Much higher mass storage capacities are expected to be achieved with other HEA, consisting of lighter elements. In the project, we will design, prepare and fully characterize a series of new HEA with a low density of <7 g.cm-3. Materials that meet the targets of absorption capacity (>2wt% and>220 kgH2/m3), low desorption temperature <140°C and high cyclic absorption/desorption stability (>1000 cycles with a capacity drop of less than 10%). In the project, we will use our knowledge and expertise in the design and preparation of HEA.

Program: SRDA
Project leader: Ing. Ballóková Beáta, PhD.
Annotation: The overall objective of NOVEMBER is to prepare and characterize new materials and concepts with self-healing functionalities integrated within the battery cell. These new composite 3-D materials will enable a variety of critical features including fail-safe and self-healing technologies to improve the battery performance, and greatly extended lifetimes. Special emphasis will be on in-operando electrochemical measurements using impedance spectroscopy and structural measurements. Validation of new materials will be done in small laboratory prototypes. This small prototypes are important in order to demonstrate scalability to battery cell production processes. To reach this goal, NOVEMBER has identified three specific objectives: 1. Development of novel high entropy oxides and sulfur based materials with self-healing functionalities. 2. Development of new physico-chemical in-operando techniques and solutions for monitoring of agign and degradation mechanisms 3. Validation and exploitation of the developed materials in prototypes. In summary, this project combines materials research advances and sophisticated in-operando technology development in order to obtain new materials for post Li -ion batteries with enhanced life-time and performances.

Program: SRDA
Project leader: RNDr. Džupon Miroslav, PhD.
Annotation: The project is focused on the restoration of functional surfaces by laser weld overlying. Innovative approaches willbe applied in the restoration of functional parts of molds for high-pressure die casting of aluminum alloys. Laserweld overlaying technology will be used for the formation of restoration layers in order to significantly reduce thenegative impact of the introduced heat on the quality of sub-weld layers. Newly designed additional materialsbased on Co, Ni, Fe with the presence of dispersed abrasion-resistant precipitates will be used. Additionalmaterials for laser welding will be used in the form of wires made of Uddeholm Dievar and Maraging. For bettervariability of the chemical composition, powder additives based on Fe with the addition of B, Ti, Nb, Mo, V and Wwill also be used to create weld overlays. The optimal method of heat treatment of weld overlays will be proposed.Research will further focus on microtexturing the surface of molded parts by low-energy laser radiation usinginnovative engraving surface treatment methods (LBT and EBT) in order to ensure a smooth distribution of theseparating agent on the mold surface. Experimental work will be focused on modifying the microgeometry of thesurface of new and renovated shaped parts of molds so that in the phase of "run-in of the mold" a compact layer ofthe separating agent is created to increase the technological life of molds. PVD and PE-CVD technologies will beused for this purpose.

HydroHEA – Výskum a vývoj nových vysokoentropických zliatin určených na efektívne uskladnenie vodíka v energetických aplikáciách
Research and development of new high – entropy alloys for efficient hydrogen storage in energy applications
Program: SRDA
Project leader: doc. Ing. Saksl Karel, DrSc.
Annotation: The presented project aims to development and research of metal hydride materials of the latest generation – highentropyalloys, which report the highest volumetric storage capacity of hydrogen among all materials used so far.We intend to utilize these materials in metal hydride tanks of hydrogen compressors, which are being developed inSlovakia by the project cooperating organisation – FME TUKE.In June 2020, the European Commission presented the Union\’s hydrogen strategy, which states that hydrogen andthe hydrogen economy are among the key technologies for the future of industry in the EU.The presented project aims to meet the goal of efficient and safe hydrogen storage. Up to date studies show thehighest volumetric hydrogen storage capacity of 150 kg/m3, out of all conventional alloys, is reached by Mg2FeH6metal hydride. In 2016, Sahlberg et al. in a publication entitled "Superior hydrogen storage in high entropy alloys"confirmed that the high-entropy alloy TiVZrNbHf can store an incredible "superior" of 210 kg/m3 of hydrogen in itsstructure with a ratio of hydrogen atoms to metal (H / M) 2.5. However, the problem of the alloy is its relatively high density of 7.81 g/cm3, which makes it too high for transport applications. In the project, we will design, prepare andfully characterize a series of completely new high-entropy materials with a low density <7 g/cm3. Materials thatmeet the targets of absorption capacity (> 2 wt% and> 220 kg H2/m3), low desorption temperature (<140C) andhigh cyclic absorption / desorption stability (> 1000 cycles with capacity drop of less than 10%) we will patent. Thealloys will also be tested in a hydrogen compressor, which will undoubtedly contribute to the further evaluation ofthe outputs of this project. In the project we will use our long-term knowledge and expertise in the design,preparation and characterization of high-entropy alloys.

BiAll-2 – Vývoj nových bioresorbovateľných zliatin pre vnútrotelové implantáty
Development of new bioresorbable alloys for intracorporeal implants
Program: SRDA
Project leader: Ing. Molčanová Zuzana, PhD.
Annotation: The main goal of submitted project is to develop the new bioresorbable alloys Ca-Mg-Zn-NN and Ca-Mg-Sr-NNwith controlled rate of biodegradation (NN are solid solution strengthening and stabilizing elements). Developed alloys will be preferentially dedicated to fabrication of intracorporal implants for bone tissue engineering field. Members of project research team are highly focused on the investigation of these alloys systems since 2014. Essential and logical continuity of research activities are moving towards to experimental outputs into medical practice. However, this requires a large-scale investments of research capabilities to enhance the plastic deformability of alloys, while maintain their excellent strength properties and slow dissolution rate. Taking into account that healing of traumatic injuries needs different time of implant mechanical support, the great ambition of the project is to prepare alloys with possibility of controlling their dissolution rate. Another research point with hugepotential of success is handling and mastering of 3D printing of well -defined intracorporal implants from proposed alloys. One of the final research tasks will be in-vivo testing of implants dissolution in the environment of animals bone tissue and continuous monitoring of their degredation rate. Several state-of-the-art experimental techniques, such as HR-TEM microscopy or experiments using synchrotron and neutron diffraction techniques, will be used to study the atomic structure and microstructure of materials to meet the project objectives. Modern techniques of selective laser sintering and/or melting will be used for the production of final implants. The achieved outputs of the project research programme will be adapted by contracted private company Biomedical Engineering s.r.o. and displayed into clinical practice.

Thermoelectric material Ag2S as green converter of heat from human body into electricity
Program: SRDA
Project leader: doc. Ing. Saksl Karel, DrSc.
Annotation: A carbon neutral society demands the development of efficient and energy saving technologies. Efficient thermoelectric devices have great potential to convert the waste heat from power plants, automotive engines, andindustrial processes into fruitful electricity. Another natural source of heat is our body. As the heat released by the human body is given for “free” wearable renewable energy generators (or harvesters) have potential to trigger revolution in the electronics industry in 21st century. For example, bendable, scalable, portable, and lightweight thermoelectrics can in future sourced flexible displays, medical image sensors, smart wearables, and large-area epapers to name a few. To date, state-of-the-art thermoelectrics is based on inorganic semiconductors that afford high electron mobility but lack in mechanical flexibility. By contrast, organic materials are amply flexible but low in electrical mobility and power output; the inorganic-organic hybrid design is a viable material-level option but has critical device-level issues for practical application. In flexible full-inorganic devices made of such Ag2S-based materials, high electrical mobility yielded a normalized maximum power density up to 0.08 W•m-1 near room temperature under a temperature difference of 20 K, orders of magnitude higher than organic devices and organic-inorganic hybrid devices. These results promised an emerging paradigm and market of wearable thermoelectrics.

FEGAFAB – Development of technology for the manufacture of FeGa-based alloys for high-frequency devices.
Development of technology for the manufacture of FeGa-based alloys for high-frequency devices.
Program: MoRePro
Project leader: Ing. Milyutin Vasily, PhD
Annotation: The iron-gallium alloy has the great prospect of widespread use in industry, as a material for the production of modern smart systems, including those operating at elevated temperatures, mechanical loads, and high frequency magnetization fields. This is due to the number of unique functional characteristics, namely, large tetragonal magnetostriction in small magnetic fields, weak hysteresis, high Curie temperature and weak dependence of properties on temperature, moreover, this alloy has relatively good mechanical properties, which makes it possible to produce thin sheets from it for use in high-frequency devices, such as ultrasound transducers and dispersants. For this purpose, it is necessary to create a given crystallographic texture and microstructure by selecting the optimal modes of rolling and annealing, which is impossible without comprehensive studies of the patterns of structural evolution in this alloy. Despite the good mechanical properties compared to, for example, Terfenol-D, the problem of FeGa double alloy is low plasticity, which can lead to cracking during rolling, which makes it difficult to manufacture sheets of this alloy in industrial conditions. The first way to solve this problem in the project is small additions of alloying elements, which lead to a significant increase in plasticity. We will study the processes of structure and crystallographic texture formation in double and doped alloys, their correlation with the modes of thermomechanical processing, the establishment of the physical causes of such a correlation. The second way is use of new achievements of powder metallurgy for FeGa compaction. This will significantly reduce magnetic loses without the need for thin sheet, but at the same time reduce magnetostriction, our task is find a balance. The purpouse of the project is comprehensive study of the structure formation processes in the FeGa alloy under different conditions and the development of optimal fabrication regimes.

Dizajn topografie povrchov nástrojov z WC-Co s aplikovanými PVD povlakmi
Design surface topography tools from the WC-Co applied PVD coating
Program: VEGA
Project leader: Ing. Jakubéczyová Dagmar, CSc.
Annotation: The aim of the project is to solve the partial role of the optimization process of Ni-super alloys used in the aircraft industry, specifically in jet engines. In the machining of Ni-superalloys, a high thermal and mechanical load occurs in the active area of the tool, reducing its lifetime and decreasing production efficiency. The challenge is the design and experimental verification of the new surface texture design of the active parts of the machining tool from WC-Co, the laser pre-treatment technology and the PVD coating of the 4th generation. Surface topography of the active part of the instrument will be modified by impulse laser radiation with controlled energy density and controlled area distribution of the heat exposed areas. The resulting surface of the active part of the tool will contain microcraters at the desired depth profile positions. The output will be an innovated texture of the tool surface in order to make machining of special nickel superalloys more effective – Inconel 713, resp. 718.

Inovatívne postupy vo výskume a vývoji nových feroických materiálov s využitím komplexnej impedančnej spektroskopie
Innovative approaches to research and development of novel ferroic materials by using complex impedance spectroscopy
Program: VEGA
Project leader: RNDr. Kovaľ Vladimír, DrSc.
Annotation: Ferroelectric and multiferroic (e.g., magnetoelectric) materials have received extensive attention in the last few decades, primarily because of their numerous potential applications in microelectronics and spintronics. Ferroic ceramics, however, suffer usually from high losses, leakage currents and low polarization (ferroelectric and/or magnetic) due to grain boundary effects and interfacial polarization phenomena. These microstructural featuresimpede largely commercial viability of electro-active ceramics. The main goal of the proposed project is to employ the AC complex impedance technique for probing the electrical properties of functional ceramics and reveal the correlation between the microstructural features and conductivity phenomena in grain boundary and/or interfacial layer dominated materials. Understanding the structure-property relationship would allow designing novel (multi-) functional materials with improved dielectric and (multi-) ferroic properties.

The core of the project consist of CAE analyses and predictions of laser welds microstructure, weldability and formability of laser welded blanks made of combined steels. Verified methodologies for the weldability and the formability prediction should contribute to include more knowledge and less material when design thin-walled car-body components. Thus, low emissions at car operation is reached, production time shortening and production costs decrease as well.

Histes – Vývoj vysoko-legovaných izotrópnych elektro ocelí pre trakčné motory elektromobilov
Development of high-alloy isotropic electrical steels for traction engines of electric vehicles
Program: SRDA
Project leader: RNDr. Kováč František, CSc.
Annotation: In this project, for the production of high strength electrical steel type “finish”, we aim to propose an original concept of chemical composition and microstructural design with the desirable crystallographic texture which would beprovided a combination of excellent electro-magnetic and high strength properties. The strength properties will be provided by high alloying of steels which are based on substituents elements with Si content from 3 to 3,5 wt.%, Alcontent from 0,5 to 1,5 wt.%, Cu content up to 0,5 wt.%, and P content up 0,10 wt.%. The low value of watt losses and high level of magnetic induction will be achieved by means of coarse-grained columnar or coarse-grained equiaxial microstructure with average grain size in the range from 150 to 300μm and with increased intensity of cube and Goss texture components at the expense of deformation texture. The evolution of the final microstructure will be based on the use of the strain-induced growth of ferrite grains through the thickness of the sheet from itssurface to the central part. At the same time, we want to eliminate the liability to the brittle failure of materials during the cold rolling. It will be realised by optimization of previous thermal deformation exposures in the hot rollingprocess as well as optimization of deformation process of cold rolling with "tailor-made" parameters of rolled steel.The development steel will be used in traction engines of electric vehicles and in high-speed electric motors withhigh requirement for the power.

Increasing the efficiency of forming and joining parts of hybrid car bodies
Program: SRDA
Project leader: RNDr. Džupon Miroslav, PhD.
Annotation: Nowadays, there is a characteristic continual pressure on the emission reduction produced by the cars. Onepossible way to reduce the amount of emissions produced by the automobiles is the reduction of the bodyweight. The weight of the automobile could be reduced through the hybrid car body, which consists of differentmaterials based on the light alloys, composite materials and high-strength steel sheets. Solutions related to suchhybrid car body designs must be addressed in to the forming, but also to the joining of the individual parts ofsuch multi-material conception. The aim of the project is the optimization of the forming conditions of aluminiumalloy sheets and high-strength steel sheets to increase the process efficiency. The appropriate joining techniquewill be proposed based on the results of the analyses of the stress-strain states of the formed parts. Acomparison of strength and load-bearing capacity of the joints after different intensity of deformation and stressstrainstates will be the assumed result. Effective and innovative methods of joining of aluminium and highstrengthsteel sheets after different intensity of deformation and stress-strain states will be assessed. The resultsobtained from the optimization of the joining process of the materials made of ferrous and non-ferrous metals willallow the strength of joints to be increased.

EDEVIR – Elektrochemická detekcia vírusov
Electrochemical detection of viruses
Program: SRDA
Project leader: RNDr. Strečková Magdaléna, PhD.
Annotation: Currently, rapid diagnosis of the SARS-CoV-2 virus presence is limited by the inability to perform bed side PCR,while other assays that detect viral antigens are associated with low sensitivity and specificity. Fast and accuratediagnosis is limiting for quick patient identification, assessment of his contacts and timely epidemiologicalintervention. Affordability is also a condition for quick diagnostics. Therefore, the present project deals with basicresearch aimed at the development of an electrochemical sensor that is able to efficiently and quickly detect thepresence of the virus in biological fluids. Our goal is to study suitable electrode materials for the electrochemicalsensors development that would be able not only qualitatively but also quantitatively to determine the amount ofvirus particles in a sample. The use of these sensors will ensure fast detection (bed side test), low consumption ofmaterials needed for detection, elimination of the use of instrumental and time-consuming methods, allow patientsto self-test, which will ultimately reduce the overall consumption of personal protective equipment.The study of electrochemical sensors for virus detection will bring new knowledge about the preparation ofelectrode materials with a specific composition and morphology. One of the main benefits will be developed.

Prehodnotenie vplyvu intermetalickej fázy na procesy krehnutia žiarupevných ocelí
Re-evaluation of the effect of intermetallic phase on embrittling processes of creep-resistant steels
Program: VEGA
Project leader: Ing. Falat Ladislav, PhD.
Annotation: The project intention is to investigate the effect of intermetallic Laves phase in thermally exposed 9Cr creep-resistant steels on degradation of their mechanical and brittle-fracture properties. Microstructure evolution aimed at kinetics of precipitation and coarsening of Laves phase will be studied in dependence of the conditionsof initial heat treatment. Apart from comparison of the properties of long-term thermally exposed states (i.e. with presence of Laves phase) with the properties of initial material states without long-term thermal exposition (i.e. without Laves phase), the key task will be the study of the effect of supplemental heat treatment of thermally-exposed states (without notable effect on Laves phase precipitation/coarsening) on potential modification of the properties of creep-resistant steels. The main aim of the project is to re-evaluate and eventually complete up-to now generally accepted opinion on the Laves phase considered as the main embrittling factor in creep-resistant steels.

Double-oriented electrical steels with high and isotropic magnetic induction.
Program: VEGA
Project leader: RNDr. Kováč František, CSc.
Annotation: The project is a goal-oriented on the development of isotropic electrical steels with high induction. The idea of theproject is based on the increase of cubic texture intensity and the control of the Goss texture component in thesheet plane. The mentioned crystallographic texture will be achieved by columnar grains growth via themechanisms of diffusion-controlled and deformation-induced grain boundary motion. The intensity of the cubictexture component will be increased from sub-surface region to the central part. At the same time the highintensity of the deformation component (111) [0vw] will be eliminated at the middle part of steel. Such amicrostructural and textural state will be the basis for the isotropy of magnetic properties at a relatively low lossesand a high isotropy of magnetic induction. The output of the project will be not only the acquired knowledge infield of basic research, also will be proposed a technological process for the preparation of such a microstructure.

Effect of continual and pulsating fluid jet on microstructure, properties and integrity on materials
Program: VEGA
Project leader: doc. RNDr. Hvizdoš Pavol, DrSc.
Annotation: The project is focused on the experimental observation and assessment of the interaction of continuous and pulsating liquid jet with and pulsating water jet with frequency of 20 kHz with material. The energy of the water stream at the site of action releases the mass and causes elastic or plastic deformation, thereby initiating dynamic physical phenomena. These phenomena are manifested in the form of periodic, continuous but non-homogeneous manifestations of vibrational and acoustic emission and their subsequent dynamic manifestations in a wide frequency spectrum. The ongoing disintegration process deforms the wave – changing its shape. An analysis of the waveform change can be identified in the elastic and plastic regions. Through the dynamic signal timing, the process of interaction of the water stream with the material can be controlled, resulting in improved mechanical resistance of the surface layer, controlled change of the microstructure, elimination of delamination and residual stresses.

Designing and production of the respirator will be carried out while applying biomimetic and ergonomic principles and modern additive manufacturing technologies, and the production of multicomponent filters will be carried out while applying a combination of powder metallurgy technology and electrospinning which will facilitate combining metal filters and polymer nanofibres. Also, ceramic components produced by 3D printing will be used as a protective packaging of the used nanofibres and nanoparticles. In order to achieve the project objectives, it will be necessary to carry out the fundamental investigation of filtration efficiencies of the suggested materials with virucidal effects based on copper and ions of silver of zinc. The purpose of the project is to develop and construct testing systems intended for identification of resistance coefficients of newly developed filtration materials, filter permeability using a suitable aerosol, as well as mask penetration through the facepiece contact line. Optimisation of the shape of the respirator facepiece will be based on the analysis of biological parameters of at least 20 human facial scans; this will facilitate elimination of potential infection by particles escaping through the space around the mask.

Project leader: RNDr. Strečková Magdaléna, PhD.
Annotation: Perspective soft magnetic composites (SMCs) for various electrotechnical applications are designed as ferromagnetic powder particles coated by very thin dielectric layer. The basic parameters of such prepared SMCs are low coercivity, high value of saturation magnetization and of complex permeability. One of the most important electrical parameter is the high value of specific resistivity, which is ensured by a minimum content of appropriately selected electrical insulating coating with respect to the individual ferromagnetic powder particles completely isolated from each other. The present project is concerned with preparation and overall characterization of SMCs from i) preparation of a ferromagnetic material, ii) through the chemical synthesis of dielectric coatings and the coating process on powder particles, iii) up to final characterization of magnetic, electrical and mechanical properties of the prepared SMCs. Soft magnetic powder material (SMM) will be represented by Permalloy-type alloy (NiFe) with addition of suitable additives prepared by high energetic milling. SMM will be characterized from the microstructure and morphology point of view by use of SEM an XRD analysis. The resulting structural characteristics will be confronted with magnetic properties. The excellent SMM will be selected from prepared alloying powder and further coated by electrically insulating layer. Theprepared core/shell powders will be compacted by powder metallurgical methods (cold uniaxial pressing) and finally heat treatment. The final SMCs will be characterized from material, electrical and last but not least magnetic point of view with regard to a design of functional SMCs for the applications at moderately high frequencies.

The activity will be performed as a part of the project. The study will be directed on investigation of temperature and deformation induced structure development processes such as polygonisation, recrystallization, grain boundary motion and development of crystallographic texture. The experimental material will be electrotechnical steels with Si content up to 2,5 wt.%. Deformation energy will be used for selective growth of grains possessing cubic texture. The deformation energy will have a different intensity level that is dependent on elasticity modulus of differently oriented grains. Mathematical models of behavior of strain stress dependences for particular crystallographic orientations during cold rolling process will be developed. These models will be used for optimization of cold rolling process. The optimization will be done in order to obtain maximal gradient of deformation intensities between grains having cubic and deformation texture components. The gradient will provide a driving force that will be used during dynamical heat treatment. The aims will be a development of columnar microstructure with increased intensity of cubic texture components. The experimentally treated materials will be subjected to electromagnetic properties measurements. On the base the proposed research a new thermo-mechanical treatment process fro semi-finish electrical steels will be proposed. This proposed process will be economically more reasonable in comparison to the now existing ones and will provide better magnetic properties for steels with content of Si up to 2.5% wt.. The process also allows decreasing of the Si content in the quality grades (M 340 to M 560 – 50E) that in turn provides higher heat conductivity.

Studies of diffusion of modifying atoms and microstructure of metal-based and semiconductor-based alloys
Program: SRDA
Project leader: Mgr. Petryshynets Ivan, PhD.
Annotation: The project is focused on characterization of nano-scale precipitates and grain boundary segregdation of carbon in non-oriented electrical steel (NO ES) and development of an empirical model for assessment of relation between their morphology and core loss. Two groups of main objectives will be investigated by joint efforts of the Slovak and Slovenian groups. First, since magnetic properties of NO ES is very dependent on second phase particles (precipitates). Precipitates can have negative effects because they limit the grain growth during the final annealing and the direct negative effect is pinning of domain wall movements. The aim of the project therefore is to investigate the (nano)structures of NO ES in order to characterize the non-metallic inclusions and precipitate populations in ferrite matrix and determine the size, morphology, quantity and distribution. Purpose of the project is to produce a model for assessment of relation between size and morphology of the inclusions and (nano)precipitates and core loss.The second group of objectives consists in the studies of segregations of carbon on grain boundaries. A quite important role plays a carbon segragation at interfaces in the NO ES. This solute elemnt has an enormous effect on grain boundary migration and even very small ammount of concentration may significantly affects the recrystallization or grain growth phenomenta taking place in the NO steel during its heat treatment. However the knowladge of whow and whther indeed the carbon influence the grain boundary migration, even at small concentrations, in steel is still radumentary. This draws a need to sudy more deeply the presnce of carbon, even at small concentrations, in NO ES.Hence, the prospective results could lead to significant improvement in microstructure and texture control which have a direct affect on electromagnetic properties of NO ES.

The steels and welds have been planned for the construction of USCB-ultra-super-critical-boilers. Joints will be prepared at various technology conditions (weld metal, heat input) with two approaches of the post weld heat treatment (PWHT), namely: austenitization+tempering and tempering without austenitization. On the base of the microstructural evaluation, calculations of residual stresses, and results of mechanical tests (hardness, tensile tests at 20 adn 600°C, short trem crep test) the possibility of the omission of austenitization will be judged, that could result in decisive economical effect – energy savings and avoiding using of a large furnace for the treatmet at the temperatures above 1000°C. Experimental assesment of phase composition and thermodynamic calculations of equilibrium phases enable the investigated steels phase evolution diagrams constuction. The study of the influence of deformation on precipitation of phases in tube bends in relationship with the heat treatment used and resulted property changes is the second scope of the project, aimed to the HT optimization.

Surface treatment of high speed steel prepared by powder metallurgy
Program: VEGA
Project leader: Ing. Jakubéczyová Dagmar, CSc.
Annotation: The aims of the proposed project can be characterised as follows; a complex analysis of the materials developed during previous projects solving, consolidated by hot isostatic pressing (HIP) technology with optimised microstructure, heat treatment and excellent mechanical properties including the microstructure evaluation depending on production process conditions, intermediate product refinement and final high speed cutting tool – cutting inserts taps. The selected materials – powder high speed steel alloyed by Co and Nb resp. vanadis 30 type – will be surface treated by plasma nitridation in order to achieve higher hardness, toughness and wear resistance. The appropriate thickness of nitride coating will be defined at different time-temperature conditions and documented by microstructural analysis. The wear resistance, hardness, ultimate strength, toughness and cutting edge durability tests will be realised.
