Specific features of electrolytic-plasma quenching

Abstract

Processes in an electrolyte and a plasma layer between the liquid electrode (anode) and the solid surface of a workpiece are analyzed. A method of controlling the surface-heating power density by periodically varying the time of turning on an elevated voltage and the voltage value is grounded. This method allows one to control the rates of heating and cooling the workpiece in the range from 20 to 500°C/s and, correspondingly, to heat surface layers to a depth of 0.1–10 mm.
