Project is focused on the application of the latest theoretical models for the increase of thermal stability, structural and oxidation resistance, wear resistance, lifetime and toughness in the development of new hardthree- and multicomponent nanocomposite coatings based on Ti-, Cr-, Al- and W-nitrides by means of doping by the reactive elements and on the optimization of the newest iPVD processes with the high degree of ionization of the deposited material based on HiPIMS and HiTUS technologies.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 coatedsubstrate 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 andproperties 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.
