Document Type and Number:

WIPO Patent Application WO/2010/119865

Kind Code:

A1

Abstract:

A discharge surface treatment electrode is used in a discharge surface treatment for forming, by generating a discharge between an electrode and a work and using the generated discharge energy, an abrasion resistance coating on the surface of the work to be treated, the coating consisting of an electrode material or a substance produced by reaction of the electrode material by the discharge energy. The discharge surface treatment electrode is formed by performing a heat treatment on a green compact produced by compressing and molding a mixed powder of a stellite powder produced by a jet mill and having an average grain diameter of 3 µm or less and a metal powder produced by an atomizing method or a chemical method and having an average grain diameter of 3 µm or less.
