Effects of abnormal dissolving of oxygen in metals under the influence of electrical discharges in impulse plasma [Articol]

Abstract

The results of experimental investigations and their analysis concerning the formation of oxide pellicles by applying electrical discharges in impulse are presented in this article. It is demonstrated that the oxidation processes take place not only on the processes piece surface, but on that of the electrode-tool as well, a fact that produce its passive state. To respect the technological regime of processing the electrode-tool surface is subjected to the process of clearing or continuous renovation.
