DISCHARGE SURFACE TREATING ELECTRODE, PRODUCTION METHOD AND EVALUATION METHOD FOR DISCHARGE SURFACE TREATING ELECTRODE, DISCHARGE SURFACE TREATING DEVICE AND DISCHARGE SURFACE TREATING METHOD

摘要

A discharge surface treating electrode (12) used in a discharge surface treatment which generates a discharge between the electrode (12) and a work (11) by using as the electrode (12) a green compact formed by compacting metal, metal compound or ceramic powder, and forms, using the energy, a coating (14) consisting of an electrode material or a material formed by reacting an electrode material by a discharge energy on the surface of the work (11), wherein powder has an average particle size of 5-10 mum, contains a mixture of a component for forming a coating (12) on the work (11) and a component for not or hardly forming a carbide of at least 40 vol.%, and is molded to have a hardness ranging from B to 8B by a pencil scratch test.
