铸造铝合金作为用量最广泛的铝合金种类之一，其服役环境复杂多变。 合金在海洋或潮湿环境下服役时通常面临腐蚀引起的结构破坏、寿命降低等问题，通过适当的方法改变其微观结构，影响表面钝化膜的成分和结构，可使合金的耐腐蚀性提升。 本文综述了近年来铸造铝合金耐蚀性的研究进展，重点讨论了合金元素(如 Cu、Si)、热处理工艺及钝化膜的作用。 总结了强阴极性元素 Cu、Si 会加剧电偶腐蚀，而通过微合金化(添加微量稀土/过渡金属)调整第二相组成，或采用固溶处理减少电化学反应界面均可以提升耐蚀性；表面钝化膜的失效机制(如 Cl- 诱导点蚀)可通过多种模型解析。 最后，针对铸造铝合金钝化膜问题，提出了若干待解决的开放性问题及研究方向建议。

As one of the most widely used types of aluminium alloys, cast aluminium alloys often serve in complex andvariable environments. When used in marine or humid atmospheres, these alloys typically exhibit issues such as structuraldegradation and reduced service life due to corrosion. The adoption of appropriate methods to modify their microstructure,thereby influencing the composition and structure of the surface passive film, can enhance their corrosion resistance. Thispaper reviews recent research progress on the corrosion resistance of cast aluminium alloys, focusing on the roles ofalloying elements such as Cu and Si, heat treatment processes, and passive films. Strongly cathodic elements such as Cuand Si can exacerbate galvanic corrosion, while adjusting the composition of secondary phases through microalloying (e.g.,adding trace rare earth/transition metals) or employing solution heat treatment to reduce electrochemically active interfacescan improve corrosion resistance. The failure mechanisms of surface passive films, such as Cl--induced pitting, can beanalysed through various models. Finally, regarding the passive film of cast aluminium alloys, several questions andsuggested future research directions are proposed.
