深海腐蚀环境下钛合金海洋腐蚀的发展现状及展望

This paper reviewed the research results of titanium alloys in deep ocean corrosive environment. The present research status of titanium alloys in the deep ocean environments was summarized from corrosive characteristics of the deep oceans and corrosion modes such as the stress cracking corrosion and low-frequency fatigue corrosion. 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 importance 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 were introduced. At the same time, the main problems and future development of corrosion researches of titanium alloy in the deep ocean environments were summarized and analyzed.
