The article presents the data of experimental research to obtain a coating on the
surface of structural materials in arc discharge plasma. It is shown that the study of physical pro-
cesses, due to which the task of obtaining a coating, allows you to control the end result and moni-
tor each stage of the study. With the help of this plasma treatment technology, samples of structural
materials with specified characteristics and structure of the protective coating were obtained. The
experiment was carried out on a vacuum-arc installation VDU-1. In VDU-1, a high-current low-
voltage discharge is formed in high vacuum and develops in vapors of the electrode material under-
going erosion.The data of experiments on which it are established that at certain parameters of
plasma treatment, significant changes occur in the elemental composition and structure, which is
accompanied by changes in the physical and mechanical properties of the material surface. In par-
ticular, the modes of obtaining functional coatings with good continuity and compaction on the sur-
face of structural steels and aluminum were selected.
