| Abstract: |
| 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. |
