Thanks to its excellent mechanical properties, magnesium alloys have many potential applications in the aerospace and other fields. However, failure to adequately solve corrosion problems of magnesium alloy becomes one of the factors restricting its wide use in many industrial fields. Inspired by nature, researchers designed and fabricated bio-inspired water-repellent (superhydrophobic and slippery liquid-infused porous surface) surfaces with special wetting properties by exploring the surface microstructures of plants and animals such as lotus leaf and nepenthes pitcher, exhibiting excellent corrosion-resistant performance. This article summarizes the research progress on corrosion resistance of magnesium alloys with bio-inspired water-repellent properties in recent years. It mainly introduces the corrosion reasons, types of corrosion of magnesium alloys, and the preparation of magnesium alloys with bio-inspired water-repellent properties to improve corrosion resistance. In particular, it is widely used and effective to construct water-repellent and anti-corrosion coating on the surface of magnesium alloy by surface treatment. It is hoped that the research in this review can broaden the application range of magnesium alloys and provide a powerful reference for the future research on corrosion resistance of magnesium alloys.

由于其优异的机械性能，镁合金在航空航天等领域具有许多潜在的应用。然而，未能充分解决镁合金的腐蚀问题成为制约其在诸多工业领域广泛应用的因素之一。受大自然的启发，研究人员通过探索荷叶和猪笼草等植物和动物的表面微观结构，设计并制造了具有特殊润湿性能的仿生防水（超疏水和滑溜的多孔表面）表面，表现出优异的耐腐蚀性-耐性能。本文综述了近年来具有仿生防水性能的镁合金耐腐蚀性能的研究进展。主要介绍腐蚀的原因，镁合金的腐蚀类型，以及制备具有仿生防水性能的镁合金以提高耐腐蚀性。特别是通过表面处理在镁合金表面构建防水防腐涂层，应用广泛，效果显着。希望本综述的研究能够拓宽镁合金的应用范围，为今后镁合金耐蚀性研究提供有力的参考。
