| 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. |

| Program: | VEGA |
| Project leader: | RNDr. Kovaľ Vladimír, DrSc. |
| Annotation: | The main goal of the proposed research is to identify and describe the fundamental mechanisms involved in phase transitions in rare earth substituted BiFeO3 magnetoelectrics. Multifunctional ceramics will be prepared bymodified solid-state reaction with the selected lanthanides and various concentrations of substituting element. A thorough analysis of the dielectric response measured in wide frequency and temperature ranges will be carried out in order to evaluate the basic processes related to the magnetoelectric coupling. The effect of the introduction of rare earth ions in BiFeO3 on the phase evolution and magnetic ordering will be investigated in relation to both the rare earth concentration and variation in temperature. Understanding fundamental structure-property relationships and their connection to the stoichiometric composition would allow fabricating multifunctional ceramics with improved magnetoelectric properties for potential applications in microelectronics and spintronics. |
