Electrolytic method of surface treatment.

摘要

A working electrode (2) is positioned to form a predetermined gap between the working electrode and the surface of a work piece (4), and submerged in an electrolyte within a tank (10). Pulses are applied to the working electrode (2) to machine the work piece (4). A pair of standard electrodes (8, 9) are immersed in the electrolyte tank (10), and electric current in the form of a pulse is applied to the standard electrodes (8, 9). Current flowing between the standard electrodes (8, 9) is detected and the current density of the current flowing between the working electrode (2) and the work piece (4) is controlled in accordance with the detected current.
