The Mechanism of Electrical Erosion of Metals

Abstract : With some forms of electrical discharge, in particular in condensed spark discharge, as is known, it occurs extensive destruction of both of electrodes or one of them. This phenomenon, which obtained the name of 'electrical erosion', plays in the series/row of the practical applications of discharge very harmful role. It leads to the intense decomposition of high-voltage switches, contacts of relay, candles of the internal combustion engines and other discharge tools. At the same time, recently this phenomenon began to be utilized for metal working.
