Abstract:
In this paper，the corrosion status of aluminum alloy ship at home and abroad about the hull, the cabin, seawater pipeline, stern plate flange were analysised through the investigation. The hull protected using paint + aluminum alloy sacrificial anode had a good protective effect, but the cabin, seawater pipeline, stern plate flange had some corrosion problems because the anti-corrosion technology were not in place. Combined with marine corrosion research data accumulated by Qingdao Marine Corrosion Research Institute about aluminum alloy, the present application problems and response measures of corrosion protection technology about aluminum alloy ship was analyzed and summarized, such as sacrificial anodes, anticorrosive and antifouling coating, microarc oxidation technolog, electrical insulation technology. Thereafter, the development proposals and the problems to be solved of corrosion protection technology about aluminum alloy ship was put, in order to provide reference for designers, builders and users of aluminum alloy ship
