采用10％FeCl3·6H2O溶液和1mol／L硫酸溶液进行不同温度下的浸泡试验，以3．56％NaCl溶液和1mol／L硫酸为介质，进行不同条件下的电化学测试，对钛的缝隙腐蚀行为进行研究。实验结果表明温度对缝隙腐蚀有较大的影响：在10％FeCl3·6H2O介质中，当温度低于50℃时未发生缝隙腐蚀，当温度高于80℃，缝隙腐蚀随温度升高而增大；在1mol／L硫酸介质中，缝隙腐蚀随温度的升高而加剧；在10％FeCl3·H2O介质中，临界缝隙尺寸随温度的升高而增大。在氧化性的三氯化铁介质中的缝隙腐蚀速率明显小于还原性稀硫酸介质中的缝隙腐蚀速率。
The immersion test was carried out with 10% FeCl3 · 6H2O solution and 1mol / L sulfuric acid solution at different temperatures. Electrochemical tests were carried out under different conditions using 3.56% NaCl solution and 1 mol / L sulfuric acid as the medium, and crevice corrosion of titanium Conduct research. The experimental results show that temperature has great influence on crevice corrosion. No crevice corrosion occurs when the temperature is lower than 50 ℃ in 10% FeCl3 · 6H2O medium. When the temperature is higher than 80 ℃, the crevice corrosion increases with the increase of temperature In 1mol / L sulfuric acid medium, the crevice corrosion aggravated with the increase of temperature. In 10% FeCl3 · H2O medium, the critical pore size increased with the increase of temperature. The crevice corrosion rate in oxidizing ferric chloride media is significantly less than the crevice corrosion rate in reducing dilute sulfuric acid media.
