Within the framework of this topic a series of coatings, processes of their synthesis were created, the stability of coatings on models of zirconium alloy in simulation environment in accident and operating conditions of fuel rods was investigated, and within the current year the processes of synthesis of coatings with Cr, (Ti,Al)N, CrOx and others were optimized. Simultaneously, the composition and parameters of synthesis of more complex coatings such as oxides, nitrides based on Ti, Zr, Cr and their combinations were optimized. As a result of a comprehensive analysis of the results of the work, a series of coatings was created, which are characterized by a relatively low level of compressive stresses (more plastic than under normal conditions) and a small size of crystallites (~ 10 nm). The parameters of synthesis of carbide-carbon coatings of Ti-Al-C type are optimized. As a result, it was possible to synthesize a series of coatings characterized by a hardness of 12… 30 GPa, a relatively low Young's modulus (149 - 349 GPa), and good wear resistance. The use of an integrated approach (combining plasma-physical and plasma-chemical methods in one process) allowed to obtain diamond-like coatings with a wide range of physical and mechanical characteristics and to establish the process of synthesis of coatings with the necessary parameters for practical implementation. It is proved that the use of a pulsed power supply of a glow discharge allows 2 times (up to 3.7 μm/h) to increase the synthesis rate of diamond coatings, and optimization of the frequency and duty cycle of the pulses leads to a further increase in the synthesis rate (up to 7.5 μm/h) and corresponding reduction of energy consumption by 1.5 times.
