Abstract
Electrochemical machining of metals and alloys is accomplished by using a pulsed electric current incorporating modulated reverse electric current. Reverse (cathodic) pulses are interposed between forward (anodic) pulses. The process is useful for electrochemical shaping of metals, electrochemically polishing metal surfaces, and electrochemical deburring of metal articles. The process is especially useful for electrochemical processing of metals and alloys that readily form passive surface layers.
