Abstract
An electrode for electric discharge surface treatment is a green compact formed by molding a metal powder, a metal compound powder, or a ceramic powder, and is used for electric discharge surface treatment in which an electric discharge is generated between the electrode and a work in dielectric fluid or air to form by the electric discharge energy on a surface of the work a coat of a material of the electrode or of a substance resulting from reaction of the material due to the electric discharge energy. The material of the electrode includes a material not desired to be carbonized and a material desired to be melted, and a particle diameter of the material not desired to be carbonized is larger than a particle diameter of the material desired to be melted.
