The work contains the results of research on the development and production of vacuum equipment for the formation of functional plasma and diffusion coatings of a wide range of applications, the results of the development of scientific and technological bases for obtaining modern coatings for improving the operational properties of industrial products, materials of the practical application of coatings at enterprises in Ukraine and abroad.

A new source of vacuum-arc plasma with a filter was developed, which at high quality of plasma cleaning from macroparticles provides an 15 times increase of the speed of the cathode ark’s spot movement on a working surface of a cathode and uniformity of thickness of the coating. Scientific bases and technological process were developed of the (ta-C) deposition without hydrogen impurity from a high-performance filtered vacuum-arc plasma source for large diameter products. A method of depositing of (a-C:H) hydrogenated diamond films from HF-smoldering discharge in a hydrocarbon environment. Based on the results of fundamental and experimental studies, the industrial unit "Bulat-7" was developed.

A complex of equipment for obtaining vacuum nitride coatings has been created and it is found that increasing the number of coatings’ components leads to a significant increase in their wear and oxidation resistance. Studies of phase composition and properties of gradient diffusion coatings of TiN, TiCN systems, multicomponent coatings of systems from BN, TiN to (TiZrNbCrSi)N, (TiVZrNbHfTa N, multilayered - from Al2O3/NbN, TiN/Co to (TiZrNbTaHf)N/MoN has shown that due to the optimization of the composition and architecture of the coating a complex of physical, mechanical, chemical and thermophysical properties is provided, which corresponds to the conditions of loading on the coated products during the exploitation.

The results of the completed design and scientific-technical researches have allowed to create domestic manufacturing of products with diamond-like coatings, to use various functional coatings for increase of working capacity of products of mechanical engineering, optics elements, details of medical equipment, maintenance of decorative qualities of products and cultural building objects of Ukraine, Armenia, Belorusia, Spain, Macedonia, the Netherlands, Oman, South Korea, Russia, USA, Turkey, Turkmenistan, the Czech Republic.
