Properties of Metal–Metal Nitride Vacuum-Arc Multilayer Coatings

The physicomechanical and tribotechnical characteristics of metal–metal nitride composite multilayer coatings in air are determined by friction with 65G steel, a diamond indenter, and an abrasive belt. Friction is carried out in the speed range from 16 mm/s to 12 m/s with a load of up to 100 N. The smallest wear is recorded for the Mo/MoN composite coating, which is characterized by hardness values of about 25 GPa and a friction coefficient of 0.065. It is shown that small wear values with respect to the abrasive belt are characteristic for metal–metal nitride composite multilayer coatings.
