摘要:: 近年来，随着世界各国对海洋资源开发与利用的不断重视，航海装备得到了快速发展，对装备轻量化的需求也日益突显。铝合金因其密度小、比强度高，作为结构材料使用可以大幅度提高航海装备的运载能力和速度，而被广泛应用。但是，在海洋腐蚀环境作用下，铝合金易受到多种类型腐蚀的破坏，表现出极为特殊的腐蚀行为规律，严重影响其使用。基于国内外相关研究现状，对铝合金在不同海洋环境条件下的腐蚀类型、腐蚀行为规律、试验与研究方法等进行了综合分析，总结了存在问题，针对性地提出了解决方法和技术途径，并对此研究领域未来的发展前景进行了展望。

Abstract:: In recent years, with the increasing attention on the development and utilization of marine resources worldwide, marine equipments have been developed rapidly, and the requirements for lightweight equipment become more and more urgent. Attributed to its low density and high specific strength, aluminum alloys are widely used as structural materials to improve the carrying capacity and speed of marine equipments. However, under marine corrosive environment, aluminum alloys are susceptible to various types of corrosion, which will seriously affect its application, and aluminum alloys exhibit very special corrosion behavior. Based on the current research status, the corrosion types, the corrosion behavior, test and research methods of aluminum alloys under different marine environments were analyzed comprehensively in this article. At the same time, the existing problems were summarized, while corresponding solutions and technical approaches were also put forward. Finally, the future development prospect of this research field was proposed.
