DC electric discharge in processes surface polishes of metal products

Abstract

An electric discharge of direct current between the jet anode and the metal cathode is studied in the processes of local surface treatment of metal products at atmospheric pressure. The oscillations of the current and voltage of the discharge, the power invested in the discharge are investigated. The surface temperature of the medium in the combustion zone of the discharge was investigated. The microrelief of the product surface was studied before and after electrolyte-plasma treatment.
