Research on corrosion resistance of cast aluminum alloys is reviewed in this article. The effect of the main microstructural features of cast aluminum alloys such as secondary dendrite arm spacing (SDAS), eutectic silicon morphology, grain size, macrosegregation, microsegregation, and intermetallic compounds is discussed. Moreover, the corrosion resistance of cast aluminum alloys obtained by modern manufacturing processes such as semi-solid and additive manufacturing are analyzed. Finally, the protective effects provided by different coatings on the aluminum cast alloys—such as anodized, plasma electrolytic oxidation (PEO), and laser—is reviewed. Some conclusions and future guidelines for future works are proposed.

铸造铝合金的腐蚀：回顾

本文综述了铸造铝合金的耐蚀性研究。讨论了铸造铝合金的主要显微组织特征，如二次枝晶臂间距（SDAS），共晶硅形态，晶粒尺寸，宏观偏析，微观偏析和金属间化合物的影响。此外，分析了通过现代制造工艺（例如半固态和增材制造）获得的铸造铝合金的耐腐蚀性。最后，回顾了由不同涂层对铝铸合金提供的保护作用，例如阳极氧化，等离子电解氧化（PEO）和激光。提出了一些结论和未来工作的指导原则。
