Abstract

An electrical discharge surface treatment method for forming a coating film by generating a pulsed electrical discharge between an electrode and a workpiece in working fluid or gas using a green compact obtained by molding metal powder or metal alloy powder or a molded body obtained by heating the green compact as the electrode, and by melting an electrode material by an energy of the pulsed electrical discharge, forming a coating of the electrode material or a coating of a material obtained by a reaction of the electrode material by the energy of the pulsed electrical discharge on a surface of the workpiece, the electrical discharge surface treatment method includes generating the pulsed electrical discharge by mixing together two or more types of pulsed electrical discharges having different energies.
