On the application of a discharge with liquid electrodes for polishing metal surfaces

Abstract

The work investigates the electrical parameters of the discharge plasma with a liquid cathode and a combined porous anode. The discharge is carried out in the vertical position of the plasma column, has a volumetric multichannel structure with a pronounced diffuse structure of the electrode spots. The influence of the porous element on the stabilization of the discharge characteristics is revealed. Discharges with a liquid electrolyte cathode continue to be of great interest from the point of view of practical application and are studied in a wide range of changes in physical and geometric characteristics [1 - 4]. Discharge plasma with a liquid cathode can be most effectively used for cleaning, polishing, with simultaneous removal of fractured and relief layers, hardening, gas saturation, surface activation, improvement of mechanical and other characteristics of agricultural machinery parts. In this work, for plasma polishing, parts of the bearing assemblies of disc harrows were selected.
