Abstract

A process for making a tube electrode (102) for shaped-tube electrochemical machining (STEM) is provided. To form the tube electrode, an electrically conductive tube (130) is provided, and an electrically insulating layer (132) is coated on a peripheral surface of the tube, during which a ceramic layer is coated on at least a tip adjacent area of the peripheral surface of the tube by micro arc oxidation, or/and an enamel layer is coated on at least a tip adjacent area of the peripheral surface of the tube by a process where slurry including enamel and a binder is applied onto a surface of a substrate by spraying, brushing or dipping, and the slurry is heated and diffused at a temperature of about 300-1000 degree C. A tube electrode (102) made by the process is also provided.
