Dependence of Glow to Arc Transitions on Cathode Surface Conditions

Abstract

EARLIER workers have shown that the relative stability of glow and arc discharges on both refractory and non-refractory electrodes is seriously affected by cathode conditions such as oxide layers1, vapour clouds2, salt contaminations3 and temperature4. However, owing to the rapid destruction by the discharge of prepared cathode surfaces, it has not been possible in the past to determine in a positive manner the effects of cathode surface condition on the glow to arc transition process.
