| 摘 要： | 借助热氧化技术对TC4合金进行表面处理,以提高其表面性能。借助扫描电镜,辉光放电光谱分析仪,X射线衍射仪和X射线光电子能谱分析热氧化TC4合金的特征,采用电化学测试技术研究了热氧层和TC4合金基材在CO2饱和模拟油田采出液中的电化学腐蚀行为。结果表明:热氧化处理后,TC4合金表面生成连续、均匀的热氧化层,主要由金红石相组成。热氧化处理显著提高了TC4合金在模拟油田采出液中的耐腐蚀性能。

| Abstract: | Thermal oxidation (TO) process was conducted to realize surface treatment of TC4 alloy. Scanning electron microscope (SEM), glow discharge optical emission spectrometer (GDOES), X-ray diffraction (XRD) and X-ray photoelectron spectroscopy (XPS) were employed to analysis the characterizations of the obtained TO layer. Electrochemical corrosion behaviors of the TO layer and TC4 alloy substrate in CO2-saturated simulated oilfield medium were investigated. The results showed that the continuous and uniform TO layer was mainly composed of rutile TiO2 phase. TO treatment had significantly improve the anticorrosion property of TC4 alloy. |
