摘要
选取TA2工业纯钛为研究对象进行热氧化处理,研究热氧化处理后试样表层物相构成、显微硬度、耐磨性和在浓盐酸中的耐腐蚀性。结果表明,热氧化后TA2表面形成了金红石型TiO2氧化膜,TiO2氧化层厚度随热氧化温度升高而增加;表层显微硬度随热氧化温度升高而提高。热氧化使TA2耐磨性和在36%～38%浓盐酸中耐腐蚀性明显改善,其中700℃为改善TA2耐磨性和耐蚀性的最佳热氧化工艺。
Commercially pure titanium （CP-Ti） TA2 samples were subjected to thermal oxidation treatment at different temperatures. The surface phase characteristics, surface micro-hardness, wear resistance and corrosion resistance in 36%-38% HC1 were investigated. The results show that rutile TiO2 coating was formed on the surface after thermal-oxidation; the depth of TiO2 layer and the surface micro-hardness increased with the temperatures. In addition, the wear resistance and corrosion resistance in 36%-38% HC1 increased significantly after thermal oxidation, which offers the optimum wear resistance and corrosion resistance after thermal oxidation at 700 ℃.
