ELECTRIC DISCHARGE SURFACE TREATMENT

摘要

An electrode used in combination with an electric spark machine for surface treatment, is comprised of a mixed powder including a powder of aluminum at a ratio of 5 - 18 weight % to the total of the mixed powder or a powder of any metal selected from the group consisting of nickel, cobalt, and iron at a ratio of 5 - 40 weight % to the total of the mixed powder and a powder of titanium hydride, wherein the mixed powder is formed by molding and sintering into a structure so dimensioned as to be incorporated in the electric spark machine as an electrode therefor.
