Abstract
The IR‐free anode potential and the current efficiency were studied for the electrochemical machining of mild steel in . The results show that an electronically conductive oxide film is present in the low current density region where the current is consumed in oxygen generation. With increasing current density, the film begins to break up with the formation of pits in the film. The film finally disappears in the high current density region where the metal dissolution takes place with a current efficiency greater than 100% and the metal surface is polished due to the presence of a precipitated salt layer with high ionic conductivity.Keywords
