Effect of the state of surface of electrodes on stability of glow discharge under welding conditions

Abstract
The effect of cathode processes on stability of the glow discharge is determined. It is shown that under conditions of heating by the high-current glow discharge the presence of non-uniform dielectric films on the anode surface caused by its contamination during operation leads to formation on the anode of local regions with a higher current density, which promote transformation of the glow discharge into the arc one.
Keywords: electrodes, low-temperature plasma, glow discharge, stability, surface state
