Deep Sea Corrosion Behavior of Typical Metal Materials and Research Hotspot Discussion

Research progresses on deep-sea corrosion behaviors and characteristics of carbon / low alloy steels, stainless steels, copper, aluminum and titanium alloys were reviewed. Considering the harshness and uniqueness of deep-sea environments, several important research directions in the relative areas of deep-sea field exposure tests and in-situ electrochemical testing technology were discussed, which mainly included the large-scale environmental test of the deeper sea in China and the real sea electrochemical testing technology achieving the acquisition and remote transmission of electrochemical data under the higher hydrostatic pressure. Meanwhile, research focuses of laboratory deep-sea simulation test field were introduced from aspects of cathodic protection, simulation prediction, stress corrosion and coating protection. At last, further developing prospects of typical materials deep-sea corrosion data accumulation and applicability research were forecast.
