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.

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.

Project leader: doc. RNDr. Hvizdoš Pavol, DrSc.
Annotation: Extension of lifetime and enhancing the thermal stability of steel used for construction of exhaust pipes, heat exchangers in waste incinerators, and casting and melting aggregates in steel and glass production can be achieved via suitable anti-corrosion coatings. The aim of this project is development of new types of composite anti-corrosion protective layers, based on ceramics prepared by controlled pyrolysis of organosilicon precursors. The use of organosilicon precursors facilitates application of conventional coating technologies, such as spray and dip-coating, with subsequent pyrolysis and conversion of the precursor to amorphous ceramics. Increased thermal stability, corrosion resistance, and minimisation of volume changes related to conversion of the organic precursor to ceramics will be achieved through the addition of suitable active and passive oxide glass fillers prepared by flame synthesis in the form of microspheres.The flame synthesis facilitates the preparation of glasses with high melting point, which ensures increase of the maximum operation temperature of the coating up to 1400 oC, as well as increased oxidation and corrosion resistance of prepared coatings, optimum compatibility of the filler with ceramic matrix and metallic substrate and, due to spherical shape of glass microparticles, also negligible influence on the rheology of the system polymer-filler in the course of coating on metallic substrate.

Annotation: In the last decade, hard coatings based on nitrides or carbonitrides of transition metals play significant role inincreasing the lifetime of the cutting and forming tools, but also in specific products of mobile devices. The mainrequirement for this type of material is high hardness and abrasion resistance. However, in the case of dynamicloading and frequent alternation of heat cycles, the adhesion of the coating to the substrate is the decisive factor.The project is just focused to this area with the main aim to find and optimize physical processes to enhance theadhesion ability of selected types of coatings and create a mathematical model that could describe the physicalprocesses involved. The specific goal is to verify the influence of the initial state of the substrate surface prior tothe coatings deposition both in terms of structural, thermal and deformation characteristics of thecoatingsubstrate phase interface. Different methods for cleaning of substrates, surface exposition and depositiontechnologies will be utilized for these tasks. The techniques of plasma, magnetron and ion sputtering as well ascathodic arc evaporation will be mainly used. The experimental methods such as electron microscopy, X-raydiffraction analysis, Auger electron spectroscopy and optical emission spectroscopy as well as a special ionbeam/ matter interaction based techniques (RBS, PIXE) will be utilized for the study and explanation of processes that could occur at the coating/substrate phase interface. The method of FEM will be used for theclarification of effects of both internal and residual stresses to the coating/substrate interface character.
