Propagation of a Liquid Inorganic Discharge on the Surface of Materials

Abstract

Plasma cleaning with simultaneous polishing by a jet electric discharge is more efficient than electrochemical polishing. The paper discusses the processes arising during the interaction of an electric discharge with solutions of inorganic substances, and studies the propagation of an inorganic discharge in a liquid on the surface of various materials (NaCl, NH₄NO₃, and discharge in glycerol). A NH₄NO₃ solution is shown to be the most effective electrolyte. We report on current‒voltage characteristics obtained for an electric discharge between a jet electrolytic cathode and a solid anode, as well as for a multichannel discharge in a jet electrolytic cathode at different jet lengths and diameters.
