A brief analysis of the most common methods for producing multicomponent alloys, including high-entropy alloys (HES), is presented in terms of their use as an alternative to coatings made of traditional structural metal materials. Preliminary studies of the microstructure and phase composition of the coating obtained by plasma deposition of FeCoCrAlTiCuMo powder in the equiatomic ratio of components are presented . The results of the research showed the possibility of obtaining a multicomponent single-phase solid solution by plasma sputtering and indicated the feasibility of its further study.

The prerequisites for the use of atmospheric plasma spraying processes with multiple reflow and hardening of coatings are considered as a method of obtaining a highly entropic structure in them as applied to wear-resistant coatings.
