Abstract
The coatings based on (Ti-Zr-Nb)N were fabricated by vacuum-arc deposition of the Ti+Zr+Nb cathodes in
the nitrogen atmosphere. Their physical and mechanical properties as well as tribological characteristics have
been studied. The coatings are characterized by a columnar structure, their hardness reaches 44.57 GPa. The
adhesion strength of coatings reaches 66.77 GPa, the friction coefficient of the «cover – Al2O3» is 1.1. It has
been determined, that the hardness of the investigated coatings significantly depends on the pressure of the
reaction gas. The coatings are promising as protective coatings for friction pairs and cutting tools.
