Investigation of the influence of the parameters of ion-plasma modification processes on the structural features and protective properties of coatings. Achieved by the developing equipment and processes of ion-plasma synthesis of the functional coatings based on nitrides, oxynitrides (carbides) of metals, diamond-like carbon and polycrystalline diamond, which are characterized by record values of physical and mechanical, chemical, tribological properties popup.description2 Complex of scientific and technical tasks have been solved in the creation, optimization, and implementation of technological processes and equipment elements for combined ion-plasma treatment, including the synthesis of functional coatings for strengthening and protecting the surfaces of steels, titanium and zirconium alloys, and tool materials. The physical and technological foundations for the formation of transition layers and the production of coatings based on nitrides, oxynitrides, transition metal carbides, diamond-like carbon, and polycrystalline diamond have been developed. Theoretical studies within the framework of the nonlocal thermoelastic peak model have elucidated the mechanisms of sp³ bond formation, nanostructure nucleation, stress evolution, and erosion in carbon coatings, providing a scientific basis for the controlled synthesis of diamond-like layers. The regularities of the formation of the structure and properties of vacuum arc coatings based on ta-C, a C:N, Ti-Al-N, Cr-Al-N, and MAX phases have been generalized. The role of doping, the creation of nanocomposite and multilayer structures, and the application of high-voltage pulsed substrate potential in increasing their thermal stability, hardness, and wear resistance have been demonstrated. The latest coatings of CrON, CrVN, VON, VN, NbN, VMoN systems, as well as thick diamond-like and diamond coatings with controlled properties have been obtained. Complex surface modification technologies have been developed for parts operating in specific conditions, in particular for steam turbine components, gas compressor seals, and medical implants, which have been successfully applied to industrial product samples. CVD deposition processes for diamond coatings for cutting tools have been developed, which have increased their wear resistance by more than 1.5 times and improved the quality of machined surfaces.
