Ti–Cr–N coatings obtained by vacuum arc deposition as a basis for creating hybrid coatings

The results of studies of Ti–Cr–N coatings synthesized on steel substrates by vacuum-arc deposition are presented. It is established that by increasing the chromium concentration to 17 at.% it is possible to achieve an increase in microhardness up to 70% and a decrease in the friction coefficient up to 50% compared to mononitride titanium nitride coatings. The possibility of synthesis of this type of coating from cross-linked particles of few-layer graphene as the first step to create hybrid coatings is also experimentally demonstrated.
