Abstract

An extensive amount of experimental material on investigation of the dependence of the erosion of a copper cathode on the main operating parameters — the current, the electrode temperature, and the magnetic field — has been generalized with the use of the thermal macroscopic erosion model proposed earlier. It has been shown that the basic regularities of the erosion, modeled in such a manner, are confirmed experimentally with a satisfactory correlation.
