To explore the surface technology for corrosion protection of magnesium alloys, biomimetic anticorrosion surfaces such as superhydrophobic and slippery surfaces have received extensive attention in the past decade. This paper summarizes typical bionic superhydrophobic anticorrosion methods for preparing magnesium alloy surface, including electrochemical deposition, chemical etching, anodic oxidation, laser etching, spraying and so on, and discusses the characteristics of each preparation method and the research progress of bioinspired surface anticorrosion of magnesium alloy. In addition, the paper also summarizes the commonly used methods for preparing anticorrosion slippery surface of magnesium alloy, which means constructing structured substrate first and then injecting lubricant, and one-step spraying method. The research progress of slippery anticorrosion surface of magnesium alloy is discussed. Finally, the challenges and future development directions of superhydrophobic and slippery surfaces of magnesium alloys are summarized.
