The authors worked out a new method of combined electric-erosion and electric-chemical processing of dielectrics in an electrolytic medium. This article is dedicated to the study of the process of passing an electric current through an aqueous solution of an electrolyte. With the help of measurements of the volt–ampere characteristics of the current passing through the electrolytes under study, the total character of the elec- trolytes’ dependence, which has 4 transition regimes, was determined. The characteristics of the transition regimes depend on both the electric regimes and the types of electrolytes and their concentration and don’t depend on the distance between the electrodes. It’s characteristic of the third phase that a plasma envelope appears that is accompanied by distraction of the dielectric. It’s shown that the tension and corresponding current density at which the plasma envelope occurs exist for every type of electrolyte when the material of the cathode is not changed. The correlation between these parameters and the coefficient of the surface-tension of the studied electrolytes is determined. The results of the study include the dependence of the speed of the volumetric broaching upon such technological parameters as the electric power, the frequency of the revolution of the electrode device, the frequency of the relaxation of the generator, and the concentration of the electrolyte. The problem of the mechanisms of the influence of the electric discharge in the electrolyte upon dielectric is discussed.
