The article describes the results of experimental studies of the parameters of the cathode potential drop in electrical discharges for different cathode materials. Contains the statistical parameters of the distribution function of the cathode. The technique of testing cathode materials for erosion resistance. It is shown that for the study of cathode processes necessary to use statistical methods of analysis. Shows a diagram of the experimental setup allows the study of the erosion resistance of different cathode materials. The graphs of the density distribution of the oscillation frequency of the spectrum, and the schedule of the experimental dependence of the oscillation frequency of the current, which is determined by the erosion resistance of cathode materials. On the basis of the test method cathode materials determined the optimum area for switching currents of specific materials.
