Zusammenfassung:	PROBLEM TO BE SOLVED: To provide a coating formation method using plasma electrolytic oxidation capable of forming a coating having high corrosion resistance, by plasma electrolytic oxidation processing, on a surface of a metal.SOLUTION: A plasma arc is generated between a metal and an electrolyte, in a state in which the metal as an anode is immersed in the electrolyte containing a water-soluble compound, for forming a coating on a surface of the metal, then, the metal on which the coating is formed is subjected to heat processing.SELECTED DRAWING: Figure 2 【課題】金属の表面に対して、プラズマ電解酸化処理により耐食性の高い皮膜を形成することができるプラズマ電解酸化による皮膜形成方法を提供することを目的とする。【解決手段】水溶性化合物を含有する電解液に金属を陽極として浸漬させた状態で、金属と電解液との間にプラズマ放電を発生させて、金属の表面に皮膜を形成し、皮膜が形成された金属を熱処理する。【選択図】図２
