    摘要: A surface treating method uses an electric discharge machining to form a coating layer having strong adhesion and excellent characteristics on a metal surface such as a hard metal. A discharge electrode is formed by powders containing metal hydride. Electric discharge is generated in a working fluid containing carbon between the discharge electrode and a workpiece. Thus, a coating layer of the metal hydride is formed on a surface of the workpiece.
