Abstract

We have used optical spectroscopy to study the radial temperature profiles for an electric arc plasma between silver electrodes and electrodes made from composite materials based on silver (Ag-CdO). We studied the structural changes in the working layers of the electrodes by metallography. We established that the parameters of the arc discharge plasma are determined by the condition of the electrode surface.
