Erosion of a Copper Cathode in a Nonstationary Arc Spot. III. Generalization of Experimental Results and Modeling of the Influence of Velocity on Erosion

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.[PUBLICATION ABSTRACT]
