The aim of the work is to develop functional protective coatings using efficient and energy-saving application technologies and to establish their optimal condition, composition and performance properties, which will increase the durability of coated carbide tools for processing alloys when restoring military equipment components. Taking into account the amount of funding provided, the tasks of the work are as follows: - to form multilayer coatings using ion-plasma methods with different physical and technological parameters of deposition; - to study experimentally the topology of the coating surface, cross-sectional structure, microstructure of individual layers, phase interface between layers and between the base and the coating, and to determine the effect of deposition process conditions on them. - Determine the mechanical and tribological characteristics of coatings under different conditions (changes in load force, medium, contact counterbody); - to establish physical and technological processes and structural-phase mechanisms that determine the formation of coatings with optimal performance properties; - to test the tool with the developed protective coatings in operational conditions; - formulate proposals for adjusting the technological process of coating deposition to optimize the structural and phase state of the coating for specific operating conditions
