Abstract

An electrolytic processing method for electrolytically processing the surface of a metallic member. A paste containing an electrolyte is prepared by mixing a paste-forming agent with a liquid electrolyte. The paste is placed between the metallic member and an opposing electrode. The metallic member and the opposing electrode are connected to an electrical power supply so that an electrical current is made to flow between the metallic member and the opposing electrode through the paste containing electrolyte, whereby the surface of the metallic member is electrolytically processed. Descaling, passivity treatment, coloring, polishing, plating and other electrolytic process can be performed on any type of metallic member at any desired place, by suitably selecting factors such as the compositon of the paste, condition of the electrical power supply and so forth.
