Object of research - fundamental processes of structural condition formation and the possibility of directional change depending on the preparation conditions and post-condensation thermal radiation treatment. The aim of the work - to establish criteria for the use of a scientific approach to the structural engineering method to create multi-layer vacuum-arc nitride coatings and on their basis to obtain wear resistant coatings with high hardness for standard application modes, and for use in conditions of extreme external effects (thermal, radiation (including ion irradiation), working in a chemically active environment). Research methods - scanning and transmission electron microscopy of high-resolution, X-ray diffraction methods, X-ray fluorescence elemental analysis, measuring the strength and electrical properties. It has been shown that controlling the structural state (structural engineering) can achieve the necessary functional characteristics of the multilayer coating, as well as their reproducibility, it is very important for industrial application development. The most important physical - technological parameters which determine the structural state of the layers in the coating include the bias potential applied to the substrate during deposition (US), the thickness of the layers in the period (?) and the pressure of the working environment (P).
