The structure and properties of the coatings obtained by vacuum-arc evaporation of the experimental sintered cathodes of Ti-Al composition were studied for comparison with the conventionally used titanium and titaniumaluminum metallurgical cathodes. It was established that the coatings of the powder cathodes contain nanocrystalline components, have ultrahigh hardness and wear resistance, and have a low coefficient of friction against steel. The surface roughness of the coatings deposited by evaporation of the experimental powder cathodes is significantly less than that of coatings deposited during simultaneous separate evaporation of single-element titanium and aluminum cathodes.
