The paper has studied the phenomena of heating of the active sacrificial anode and the distribution of heat flow under jet focused electrolytic-plasma treatment. We have assessed the temperature distribution on the anode surface using measurements by an artificial thermocouple and by fuse indicators. We have measured the temperature of the basic elements of the system consisting of the anode, the cathode, the electrolyte (under drainage from the sample and in the receiving tank), and the vapor-gas medium (in the vapor trap and in the working chamber housing). It was found that if the localized beam was focused on the anode surface area substantially greater than that of the cathode, occurs low-temperature processing of the surface layer of the material occurred in a low-velocity electrolyte jet, which provides polishing of the steels without undergoing phase transformations. The distribution of heat flows under jet focused electrolytic-plasma treatment was analyzed.
