The object of this study is composite multicomponent nanostructured coatings, which are used to increase the durability of the working surfaces of valves operated at critical facilities in the petrochemical and nuclear industries. The aim of thestudy is to experimentally determine the main characteristics of coatings Ti-TiN-(Ti, Mo, Al)N, Ti-CrN-(Cr, Mo, Al)N, Ti-Zr-ZrN-(Zr, Mo, Al)N obtained by the method of substance condensation by cathodevacuum-arc deposition with filtration of the microdroplet phase, and to select the most preferable characteristics for shutoff valves. To determine the coefficient of dry friction, tribological tests were carried out, instrumental indentation was used to establish the hardness of the samples, and the roughness was determined by the profile method. It was found that the best values of the studied characteristics, namely, indentation hardness (38.9 GPa) and roughness (average profile deviation is 0.242 μm), according to the test results, are samples coated with Cr-CrN-(Cr, Mo, Al)N ; according to the results of tribological tests, the Cr-CrN-(Cr, Mo, Al)N coating also has the lowest friction coefficient (0.0806). A promising direction for further research may be the development and study of new multicomponent nanocomposite coatings based on high-entropy alloys.
