Abstract
A method of evaluating an electrode for discharge surface treatment for generating a discharge between the electrode and a workpiece in a treatment liquid or in the air using a green compact obtained by molding a metal, metal compound, or ceramic powder or other green compact obtained by heating the green compact as the electrode, and forming a coat consisting of an electrode material or a substance obtained by a reaction of the electrode material by a discharge energy on a surface of the workpiece, includes evaluating a capability of the electrode to deposit the coat based on an amount of deposition of the electrode material on the surface of the workpiece by a single discharge.
