The object of research were physical processes and phenomena that determine the adhesive interaction in layered systems "multicomponent coating - tool substrate". The influence of technological factors (pressure in the chamber, negative displacement potential on the substrate, cathode compositions) on the structural-phase state and properties of composites with coatings (TiAlCrY)N/ZrN, (TiZr)N/(TiSi)N, (TiAlSiY)N/CrN was investigated. Verification of the obtained fundamental data on the regularities of phase formation and evolution of the structure of coatings was carried out by testing PCBN cutting inserts, the best results are shown by the (TiAlSiY)N/CrN system. Nanoscale multilayer coatings WN/MeN (Me = Cr, Zr, Mo, Nb) were formed and investigated. The WN/NbN coating showed the highest adhesion and the best wear resistance and mechanical properties. This coating is expected to be effective as a hard protective coating for severe tribological applications.
