摘要

目前在舰船领域，关于钛合金的氢脆风险研究较少。为此，基于钛合金在舰船领域应用日趋广泛的现实情况，采用电化学测试、腐蚀仿真计算、模型腐蚀试验等手段，综合分析了钛合金在舰船领域应用的氢脆风险。结果表明：钛合金在海水介质环境中与施加有效阴极保护的船体钢直接接触时，钛合金发生氢脆风险较大。建议对所有钛合金与船体钢在海水介质环境中接触部位实施电绝缘措施，以隔断电子回路。

Abstract

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.

Key words： titanium alloy; hydrogen embrittlement; realm of warship; cathode protection
