摘要：
As the lightest metal structural material, Mg-Li alloy has a good development prospect in the fields of aerospace, military, and electronic industry. However, the poor corrosion resistance seriously limits the wide application of Mg-Li alloy, so it is important to study the corrosion mechanism and surface protection of Mg-Li alloy. Based on the research progress at home and abroad, the corrosion mechanism of Mg-Li alloy was reviewed. The surface protection methods for Mg-Li alloy, including electroplating, electroless plating, chemical transformation, anodic oxidation, overlay coating, and other methods, were systematically summarized. It is suggested that the protection mechanisms of various surface treatment methods on Mg-Li alloy should be further studied, and the anti-corrosion effects of coatings on Mg-Li alloy can be improved by the compositing, self-healing, and hydrophobing of coating. © 2022, China Science Publishing & Media Ltd.
