The properties of surface layers can be formed by changing their structure using heat treatment and their composition and structure via the supply of an additional material to a treatment zone. The structural and phase transformations in the near-surface layer are determined by the thermal cycle in a treatment zone. To control the heating spot area at a uniform energy distribution and a high energy concentration is a challenging problem for surface heat treatment and deposition (surfacing). The results of studying plasma surface heat treatment and surfacing with a reversed-polarity current are presented. The contribution of the heat transfer from nonstationary cathode spots to an article during plasma surface treatment using a reversed-polarity current is separated. The advantages of surface heat treatment of medium- and high-alloy steels and the deposition of similar and dissimilar alloys using a reversed-polarity current constricted direct arc are presented.
