An object of the present invention is to provide an electrolytic ceramic coating method of a metal which can obtain a film having a high hardness, excellent abrasion resistance, excellent toughness and low relative material aggressiveness even when applied as a sliding member without polishing. The said subject is achieved by the electrolytic ceramic coating method of the metal which electrolytically processes a metal as an anode in the electrolyte solution containing a zirconium compound, and forms a ceramic film on the said metal surface. |
