The article shows the abrasion-adhesion combination of wear-induced damage mechanisms in the vacuum ion-plasma coatings of friction surfaces acting in a wide range of contact conditions. A reduction of wear of hard-alloy cutting plates with application of vacuum-plasma nitride-zirconium microcoatings is explained by a change in the contact surfaces properties complex and by reduction in the sizes of abrasive particles with maintaining the protection properties after the coating damage.
