Abstract
A discharge surface treatment electrode used in discharge surface treatment for forming a wear-resistant film on a treatment target surface of a workpiece by use of the discharge energy of electric discharges caused between the electrode and the workpiece, the film being made of a material of an electrode or a substance obtained by a reaction of the material of the electrode with the discharge energy. The discharge surface treatment electrode is formed by: compression-molding a mixed powder into a green compact, the mixed powder being formed from a powder of a Stellite alloy with an average particle size of 3 μm or less prepared by use of a jet mill and a powder of a metal with an average particle size of 3 μm or less manufactured through an atomization process or a chemical process; and subjecting the green compact to heat treatment.
