摘要: Using a model of the continuous metal-to-plasma transition, simple formula relating arc voltage to cathode thermophysical properties, such as Lorentz constant, heat capacity and energy deposition into arc, has been derived. A for erosion rate also The ratio used compare theoretical experimental data. In view this analysis, higher than that obtained experimentally is predicted.
