1. IntroductionPlasma electrolytic oxidation (PEO) is a surface treatment technology that forms a very stable porous oxide film on base metals using a discharge phenomenon in the electrolyte [1]. A high voltage induces a spark or arc plasma discharge, creating a local high-temperature spot in the electrolyte, enabling oxidation of the metal and the rapid melting and solidification of the oxides [2,3,4].
