DEVICE FOR ELECTRICAL DISCHARGE COATING AND METHOD FOR ELECTRICAL DISCHARGE COATING

摘要

Metal powder, or a powder of a metal compound, or by using a green compact electrode by compression molding a powder of ceramic, applying a 500V or more voltage between the case of performing the discharge surface treatment, the electrode and the workpiece from a gaseous atmosphere by the pulse and generate a discharge, a film consisting of an electrode material or the electrode material to the workpiece surface by the energy to form a film consisting of a material by the discharge energy-phase pulse response.
