The study the erosion of the electrodes under the influence moving electric arc

Abstract

© Published under licence by IOP Publishing Ltd. The paper presents the results of experimental study of the processes of interaction of a moving arc with electrodes pulsed plasma generator in the range of parameters I = 60÷500 A, U 30÷70 V, G 0÷155 l/min, dE 4÷14 mm and LE 2÷20 mm. In this article the results of the study traces left by moving arc on the electrode surfaces are described, and the impact velocity of the arc on the form and sizes these traces, ranging VD 7÷130 m / s. We show the research results of the heating and erosion of the electrodes under the influence of high-current arc moving.
