Paper Abstract

A 1D nonstationary model of material melting and evaporation in anode spots of vacuum arc is developed. Calculations of melting and evaporation rates of copper and copper-chromium contacts were carried out and concentration of copper atoms was evaluated when the arc was burning and after its extinguish. The model of anode melting that accompanies its evaporation permits to assess the time of liquid metal film existence at the anode in the ablation approximation of the model.
