The aim of the work is to establish the relationship between elemental and phase states and thermal stability, mechanical and tribological properties of nanostructured protective multilayer coatings, and the influence of technological parameters of deposition, namely the working gas pressure and substarate bias. Methods of depositiong and investigation of samples - the method of vacuum-arc and magnetron deposition was used to deposite of the coatings; for the study of microstructure and cross section - scanning electron microscopy with EDS, X-ray diffractometry, transmission electron microscopy, the method of differential scanning calorimetry, the study of the distribution of the elemental composition of the samples - the method of secondary ion mass spectrometry and X-ray photoelectron spectroscopy; determined mechanical properties by the method of indentation of the coating surface. The new methods for the synthesis of promising functional coatings with improved parameters, in particular, nitrides of transition metals in multilayer complex structures are developed in the project. The technology for obtaining protective coatings with known physical and mechanical properties based on the results of complex studies of the structure, phase and elemental composition of transition metal nitride coatings: (TiZrNbTaHf) N / MoN, (TiZrNbTaHf) N / WN, TiN / SiC and a-AlN / a-BCN, ZrN / CrN, (CrN / ZrN ) / (Cr / Zr) and TiZrN / TiSiN is developed.
