| 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. |

| 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. |

The main idea is to create new nanostructural systems based on the known 2D and 3D nanocomposite systems (TiB2, Ti-B-N, Ti-Al-N, Cr-Al-N, W-C, W-C-N) doped with additional elements (Ta, V, Y, W, Nb, Si, B a pod.), which will increase toughness and crack resistance of the coatings. They will simultaneously create active barriers supressing oxidation and thus, reduce mechanical properties degradation of the coatings and/or coated substrate at elevated temperatures. The work, which is a direct continuation of the previous project APVV 0520- 10, also involves the investigation of the relationships among the deposition parameters, resulting structure and properties of new systems for hard coatings and basic understanding of the mechanisms of the nanostructure formation, metastable phase decomposition, formation of stable structures, etc. in the case of novel deposition technologies with high degree of ionization of the sputtered material. |

| Annotation: | The project deals with metal matrix composites made by powder metallurgy from coated, nanostructured or amorphous materials. Metals with nanostructured or amorphous reinforcements represent a relatively new and yet poorly understood class of materials. The project is oriented on fundamentals rather than on a specific composite development. The aim is to answer the questions: How is the powder-mass\’ behavior related to properties of individual coated, nanostructured or amorphous particles? What are the fundamental processes during compaction and sintering of such powders and how do they affect the product’s microstructure? What are the basic links between microstructure and macroscopic properties of metals with coated, nanostructured or amorphous reinforcements?Both experimental and theoretical means will be used to reach the project goals. Experiments combined with a theoretical study of model systems should contribute to the understanding of properties and potential of a given class of materials. |
