Discharge surface treating method comprises generating a pulsating discharge between an object to be surface treated and a discharge electrode containing a corrosion resistant material, e.g. chromium, in a working fluid

摘要

A pulsating discharge is generated between an object to be surface treated and a discharge electrode containing a corrosion resistant material, e.g. chromium, in a working fluid. The electrode wear fused substance of the discharge electrode produced by the energy of pulsating discharge is deposited on the surface of the object and a coating exhibiting corrosion resistance is formed on the surface of the object.
