Abstract:
1. An electrode for electric discharge surface treatment, the electrode being a molded powder that is formed by molding a material powder that is any one of a metallic powder, a metallic compound powder, and a conductive ceramic powder, the electrode used for electric discharge surface treatment in which a pulse-like electric discharge is caused between the electrode and a work in a dielectric fluid or an atmosphere, and in which a coat of an electrode material or a substance that is generated by a reaction of the electrode material due to an electric discharge energy is formed on a surface of the work, wherein a powder solid that has a diameter larger than a distance between the electrode and the work, is not included in the molded powder, the powder solid being formed as a result of coagulation of the material powder, wherein an average grain diameter of the material powder is 3 micrometers (μm) or less.
