Karazin Kharkiv National University popup.description2  The formation processes of ion-plasma functional coatings, formed by a multilayer combination of nano-sized interlayers of multicomponent nitrides and mononitrides of transition metals, were investigated at this stage. The influence of the annealing temperature on the mechanical characteristics of (TiSi)N/CrN multilayer coatings obtained at different nitrogen working pressure and negative bias potential applied to the substrate was studied. Multilayer coatings (TiSi)N/CrN were obtained by the vacuum-arc deposition method using two electric arc evaporators with chromium and titanium-silicon cathodes in the mode of continuous rotation of the substrate. The multicomponent Ti0.46Al0.20Zr0.19Nb0.07Y0.08 cathode was used to obtain coatings based on (TiAlZrNbY)N on stainless steel sheet substrates by vacuum-arc deposition technology. All coatings had a dense microstructure, although microdroplets were visible on the surface of the coatings. X-ray diffraction analysis revealed the formation of a main single-phase cubic structure with a minor wurtzite phase for coatings with a high Al content. The influence of reaction gas pressure and the number of bilayers on the mechanical and tribological characteristics of (TiZr/Nb)N multilayer coatings was studied. (TiZr/Nb)N multilayer coatings were obtained by the Arc-PVD method. The phase composition, distribution of elements, mechanical and thermal properties were investigated. Nanoindentation tests were conducted to study the mechanical properties of the coatings.
