The structure and physicomechanical characteristics of vacuum coatings formed from refractory metal compounds on steel substrates of different chemical composition are studied. The possibility of applying refractory metal coatings to protect metal substrates used for the manufacture of metalworking tools and steel tools used for casting non-ferrous metals has been analyzed.

In the present work, the adhesion and physico-mechanical characteristics of heat-resistant vacuum coatings formed on steel substrates are investigated. An increase in the values of adhesion and physico-mechanical parameters of coatings formed from multicomponent compounds is established. The tribotechnical characteristics of coatings based on chromium carbonitride have been studied.
