Hydrogen Embrittlement Risk Analysis of Titanium Alloy Applied in the Realm of Warship

At present, there are only a few researches on the hydrogen embrittlement risk of titanmium alloy in the realm of warship. Based on the reality that titanium alloys are more and more widely used in the field of warship, the hydrogen embrittlement risk of titanium alloy applied in the realm of warship was analysed by means of electrochemical test, corrosion simulation calculation and model corrosion test. Results showed that the hydrogen embrittlement risk of titanium alloy was high when it contacted directly with the cathodic - protected hull steel in seawater environment. It was recommended to take electrical insulation measures for all contact parts between titanium alloy and hull steel in seawater medium environment to cut off electronic circuits.
