摘　　要：镁合金因其优良的性能在工业和生物医用等领域表现出巨大的应用潜力。然而,镁合金在空气与潮湿环境中极易被腐蚀,限制了其广泛应用。通过在镁合金基体表面构建纳米粗糙结构,并使用低表面能物质修饰,以形成超疏水涂层,可有效防止其在空气与潮湿环境中被腐蚀。本文首先对固体表面润湿性理论进行简要介绍,随后综述近年来镁合金表面超疏水涂层的制备方法,包括蚀刻法、水热法、微弧氧化法、电沉积法、浸渍法等,分析各方法通过不同的实验条件所获得的超疏水涂层结构和性能的差异,并介绍了超疏水涂层的发展趋势。最后指出目前超疏水涂层在实际应用中存在的问题,并对未来镁合金表面超疏水涂层的发展方向进行展望。Magnesium alloys have shown great potential in industrial and biomedical fields due to their excellent properties.However,magnesium alloys are highly susceptible to corrosion in air and humidity environments,limiting their wide range of applications.By constructing a nano-rough structure on the surface of the magnesium alloy matrix and modifying it with a low surface energy substance to form a superhydrophobic coating,it can effectively isolate its exposure to air and humid environments.In this paper,the theory of solid surface wettability was briefly introduced.Then,the preparation methods of superhydrophobic coatings on the surface of magnesium alloys in recent years were reviewed,including etching method,hydrothermal method,micro-arc oxidation method,electrodeposition method,impregnation method,etc.,and the differences in the structure and properties of superhydrophobic coatings obtained by each method under different experimental conditions were analyzed,and the development trend of superhydrophobic coatings was introduced.Finally,the problems existing in the practical application of superhydrophobic coatings were pointed out,and the development direction of superhydrophobic coatings on magnesium alloy surfaces in the future was prospected.
