Abstract

Protective coatings are an effective way to increase the wear resistance of various parts, tools, and components. Ti–Al–Ta–Si–N coatings combine the benefits of the Ti–Al–Ta–N and Ti–Al–Si–N systems which provide their improved hardness, toughness, adhesion, thermal stability and oxidation resistance. In this paper, the possibility of increasing the wear resistance of Ti–Al–Ta–Si–N coatings by introducing intermediate Ta layers is investigated. It is shown that the deposition of Ti–Al–Ta–Si–N/Ta multilayer compositions with optimal layer architecture can significantly increase their wear resistance. The wear rate of Ti–Al–Ta–Si–N/Ta coatings containing 15 layers is reduced by ~3.6 times compared to the monolithic Ti–Al–Ta–Si–N coating.
