Study on Electrochemical Behavior and SCC Susceptibility of TC4 in Methanol Solution

Keywords： titanium alloy , stress corrosion , methanol solution , pitting corrosion

采用慢应变速率试验,辅以扫描电镜、金相观察等分析测试技术,研究了钛合金TC4在甲醇、盐酸-甲醇溶液中的应力腐蚀敏感性.试验结果表明,TC4钛合金在甲醇中具有应力腐蚀敏感性.甲醇中加入盐酸,明显地提高了TC4的应力腐蚀敏感性.TC4钛合金在盐酸-甲醇溶液中的应力腐蚀裂纹源自点蚀孔底部.

Stress corrosion crack (SCC) susceptibility of titanium alloy TC4 in methane and hydrochloric acid- methane solution was studied by slow strain rate tensile test (SSRT), SEM analysis and metallography observation. The experimental results show that TC4 is possessed of SCC susceptibility in methanol solution, and addition of methanol solution to hydrochloric acid- methanol solution can greatly improved the SCC susceptibility of TC4 alloy. SCC of TC4 in hydrochloric acid- mdethanol solution originates from the bottom of the corrosion pits.
