    Abstract:

    This paper reviews the research results of titanium alloys in deep ocean corrosive environment. The present research status of titanium alloys in the deep ocean environments is summarized from corrosive characteristics of the deep oceans and corrosion modes such as the stress cracking corrosion, low-frequency fatigue corrosion, etc. The failures and leakages of the titanium alloys for the applications in the deep ocean environments caused by high hydrostatic pressure from above the seawaters is of important for the applications of the deep sea stations. On the other hand, corresponding electrode reactions of titanium alloy in deep oceans are dramatically affected by the high hydrostatic pressures. The application of integrated materials calculations and simulations in the fields of metallic corrosion and the testing equipments for simulating the specific corrosion condition in the deep oceans are introduced. At the same time, the main problems and future development of corrosion researches of titanium alloy in the deep ocean environments are summarized and analyzed.
