Abstract

The effect of a low-temperature plasma of direct current electrical discharges with liquid and solid electrodes at atmospheric pressure on the surface microrelief of a product made by selective laser melting technology is studied. The electrical characteristics of the discharge, current oscillations, and discharge voltage and the power supplied to the discharge are investigated. The composition of the discharge plasma is studied and the electron density is estimated. A mechanism of the discharge formation at the interface between the metal anode (treated workpiece) and the liquid cathode is considered. The microrelief is studied using the methods of scanning electron and laser microscopy, and the roughness parameters and chemical composition of the product surface are determined before and after electrolytic-plasma treatment. The morphology and surface roughness parameters of the parts are compared after electrolyte-plasma and mechanical treatment.
