Abstract: Magnesium and its alloys have attracted much attention due to their excellent properties. However, the poor corrosion resistance severely limits its engineering application, therefore suitable methods should be developed to improve the corrosion resistance of magnesium alloys. The investigation of hydrotalcite coatings for surface modification on Mg alloys is increasingly deve-loped owing to good ion exchange ability and physical barrier effect. Several preparation methods of hydrotalcite coatings and their formation mechanism are introduced in this paper. Meanwhile, the anticorrosion mechanism of coatings under corrosive environment condition are preliminarily discussed and various modification methods to further enhance coating properties are described in detail. Finally, the focus of future research and development are expected.
