FIELD: finishing of metallic materials. SUBSTANCE: method is realized due to using DC source in liquid electrically conducting working medium and controlling width of electric current pulses. Theological liquid is used as electrically conducting working medium. Width of electric current pulse is controlled due to changing viscosity of working medium. Pause duration between electric current pulses is controlled according to time period of achieving maximum electric current of pulse. EFFECT: enhanced efficiency, improved accuracy of treatment, enlarged manufacturing possibilities of electrochemical process with pulsating current. 2 dwg, 1 ex
