Comparative friction characteristics of high-entropy mononitride coatings

Abstract

The tribotechnical characteristics of nitride coatings in a pair with a diamond on air have been determined. The friction has been applied in the range of velocities of 6–16 mm/s and loads on diamond in the range of 1.5–5.5 N. A decrease in the friction for all nitride coatings under study with a decrease in the slip velocity has been determined. The intensity of periodic wear of nitride coatings decreases with growth in the load and varies from 1.6 × 10^–6 to 5.3 × 10^–6. High-entropy nitride coating possesses higher tribotechnical characteristics relative to mononitride coatings.
