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.
