N2 - Magnesium-lithium (Mg-Li) alloys, as ultra-light structural materials, have great potential in lightweight fields such as aerospace, automobiles, and biomedical applications. However, their poor corrosion resistance restricts their engineering applications. This paper systematically reviews the latest progress in the preparation technology of surface coatings for Mg-Li alloys, with a focus on key techniques such as chemical conversion coatings, plasma electrolytic oxidation, and deposition coatings. Based on the analysis of the protective mechanism of the coatings, it systematically evaluates their multiple performance such as corrosion resistance, wear resistance, coloring, thermal control, and biocompatibility. The application potential and future directions for achieving functionality through composite coatings are also discussed, aiming to provide a reference for breaking the application bottlenecks of Mg-Li alloys.
