Abstract

Method of electrochemically processing metallic surfaces of workpieces wh are arranged in an electrolyte of an electrolysis cell in such a way that the workpiece does not contact the anode and the cathode, with pulverous particles of one of the group consisting of graphite and activated carbon being suspended in the electrolyte, with the pulverous particles being charged on the anode for transfer of an electric charge to the workpiece. The pulverous particles are shielded by a diaphragm or an ion exchange membrane so that the charged pulverous particles cannot discharge at the cathode. In the electrolyte there is dissolved one of the group consisting of a V.sup.+5 compound and a vanadium-containing compound adapted to form V.sup.+5 ions at the anode of the electrolysis cell.
