Popis: In the present work, a coating growth during plasma electrolytic oxidation on magnesium alloy was investigated. We observed the initial stages: electrochemical anodizing accompanied by anodic dissolution; oxidation with low power spark discharges; oxidation with microarc discharges. The study discusses the evolution of morphology, porosity, elemental composition in comparison with the PEO electrical characteristics and optical emission of microdischarges. The kinetic model, which is consistent with the observed mechanism of coating growth, is constructed.
