As a lightweight high-performance metallic material, magnesium alloys demonstrate significant application potential in fields such as aerospace, automotive manufacturing, and biomedical engineering. However, their high chemical reactivity leads to susceptibility to corrosion and degradation in service environments, severely limiting their engineering applications. Micro-arc oxidation (MAO) technology, also known as plasma electrolytic oxidation (PEO), effectively addresses the corrosion protection of magnesium alloys by in-situ generating a ceramic oxide layer on the metal surface. This paper systematically elaborates on the fundamental principles, process optimization, coating performance enhancement, and multidisciplinary applications of micro-arc oxidation technology for magnesium alloys. It comprehensively analyzes the current research status and development trends of this technology, providing theoretical guidance and technical references for the surface modification of magnesium alloy materials.
