| 介绍了Al-Cu， Al-Mg， Al-Si系等3种主要的船用铝合金在海洋环境中的应用和腐蚀研究现状， 对三种铝合金的性质以及在船舶及船用设备领域中的具体应用进行了概述， 对船用铝合金在不同海域海洋大气、 表层海水、 深海海洋环境下的腐蚀状况以及在模拟海水条件下的腐蚀研究进展进行了归纳。已有研究表明， 海洋环境下船用铝合金的腐蚀形式主要为点蚀和应力腐蚀， 其腐蚀程度和敏感性随海水深度的增加而增大， 相同海洋环境下Al-Mg系铝合金具有较好的耐腐蚀性能。最后综合实际生产和应用现状， 对船用铝合金的发展趋势及其在海洋环境下的腐蚀研究工作的进一步开展做了展望。 |

| In this paper, the application and current corrosion research of three series of aluminum alloys, namely Al-Cu, Al-Mg and Al-Si, in marine environment were reviewed. The properties of the three kinds of aluminum alloys and their detailed applications in the field of ships and marine equipments were briefly illustrated. The corrosion of aluminum alloys under marine atmosphere, surface seawater and deep ocean in different sea sites as well as the research progress on corrosion under simulated seawater condition was also summarized. The researches have shown that the main corrosion types of aluminum alloys for ship applications in different marine environment were pitting corrosion and stress corrosion. The degree and susceptibility of corrosion aggravate with the increase of the seawater depth. Among these three kinds of aluminum alloys, the Al-Mg series of materials show the best corrosion resistance. Finally, based on the manufacture and utility status, we prospected the research and development tendency of aluminum alloys for ship applications and the corrosion research in marine environment. |
