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.
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 compo-sition of the coating obtained by plasma deposition of FeCoCrAlTiCuMo powder in the equiatom-ic ratio of components are presented. The results of the research showed the possibility of obtain-ing a multicomponent single-phase solid solution by plasma sputtering and indicated the feasibil-ity of its further study.
Summary: a promising design for determining the hardness of paint coatings is proposed, which allows to reduce the influence of a specialist on the results obtained, which will qualitatively increase the objectivity of the results obtained.
The paper analyzes the technological equipment of the combined process of obtaining multicomponent coatings based on plasma spraying in an open atmosphere.
