【 摘 要 】

The paper presents the investigation results of the structure and properties of coatings deposited from separated vacuum-arc discharge flows based on TiN alloyed with aluminum. The influence of the coatings elemental composition on the structure, phase composition and their mechanical properties was established. It is determined that coatings containing in the hexagonal phase Ti3Al2N2 are characterized by high hardness, low friction coefficient, maximum values of elastic recovery and plastic deformation resistance.
