Abstract
An electrolytic apparatus for applying a voltage to a workpiece (1) and a counter electrode (5) both immersed in an electrolyte (3) contained in a vessel (4) thereby processing the workpiece (1) comprises a voltage source (15, 15') for applying voltage between the workpiece (1) and the counter electrode (5) in the form of pulses whose polarity is periodically changed, a beam generator (16) for irradiating a subsidiary energy beam (17) on a selected region of the workpiece (17) by generating the beam (17) in the form of periodic pulses and a timing control device (21) for synchronizing the periods of the voltage pulses and the beam pulses.
