| 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. |

| Investigation of phenomena induced by electron beam and electromagnetic radiation in chalcogenide glasses | |
| Program: | SRDA |
| Project leader: | doc. RNDr. Lofaj František, DrSc. |
| Annotation: | e-CHALCO project aims to study the interaction of the electron beam and electromagnetic radiation withsurfaces of thin films from chalcogenide glasses. In this area, we have reported recently results that lead tofundamental understanding of the phenomena induced by local interaction of electric charge andelectromagnetic radiation with these materials. In this project, we plan to continue in more systematic and deeperstudy of the effects induced during local perturbation of these materials, which can lead to local deformation,change in the chemical composition, phase transitions and charge persistence and accumulation using the latestmicroscopic, spectroscopic and diffraction techniques. We also focus on the investigation of influence ofexperimental parameters such as charge deposition lattice period, accelerating voltage, layer thickness, andcomposition of glass for the observed effects. Opportunities to prepare mesoscopic and nanoscopic structureswill lead to new applications of these materials in nanotechnology, for example, in fabrication of nanoemitters, incatalysis and in fabrication of probes for scanning probe microscopy and in technologies for recording andstoring information. |

| ZELASHYK – Zvyšovanie efektívnosti lisovania a spájania dielov hybridných karosérií | |
| 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. |

| VaTRsEDVFsOAM – Vývoj a testovanie respirátorov s efektívnou degradáciou vírusov filtrami s obsahom antivirotických materiálov | |
| Development and Testing of Respirators with Efficient Degradation of Viruses by Filters Containing Antiviral Materials | |
| Program: | SRDA |
| Project leader: | Ing. Ballóková Beáta, PhD. |
| Annotation: | In response to the situation resulting from the spread of the SARS-CoV-2 virus, the research and development performed at workplaces of the Faculty of Mechanical Engineering of the Technical University of Kosice has been partially transformed into research and development of special respirators and filtration materials. The submitted project is focussed on the development and construction of respirators with separable filters without exhalation valves which provide efficient protection against SARS-CoV-2 virus. The aim of the project is the investigation, development and production of respirators with separable filters and the testing of novel filtration materials. 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. |

| ZKVAVESE – Zvýšenie kvality výstrižkov a efektívnosti strihania elektroplechov | |
| Increasing the quality of cut-outs and effectiveness of cutting electric sheets | |
| Program: | SRDA |
| Project leader: | RNDr. Džupon Miroslav, PhD. |
| Annotation: | Electric tractions (motors) are inseparable part of many devices from the motor for home appliances through theelectric motors for machines and equipment to electric motors for electric vehicles. Most of these motors consistof the rotor and stator, which are based on the cut-outs from electrical sheets. The cut-outs are joined into therotor and stator bundles. When making the bundles, the important factor is the quality of cutting surface, whichalso influences the additional operations. It also has a significant effect on the quality parameters of electricmotors (size of losses by engine heating). The proposed project has the ambition to solve the optimization of thequality of cutting existing and new developed electrical sheets in context of the expected development ofproduction of electric vehicles. The base of the experimental part is the verification of new tool materials(including uncoated ones) for the production of the active parts of cutting tools for the purpose of increasing thequality of cutting surface and tool life and thereby increasing the efficiency of production of cut-outs fromelectrical sheets. |
