中文摘要：

选择酒石酸钠环保电解液,用恒电势法在不同浓度条件（1,5,15,30和50 g/L）下制备TA2纯钛阳极氧化膜。采用原子力显微镜分析膜层的微观三维形貌,使用电化学工作站研究试样在3.5%NaCl溶液低电位下的极化曲线和电化学交流阻抗谱,探讨微观三维形貌对耐腐蚀性能的影响。结果表明：15 g/L浓度时,氧化膜层细小均匀,生长完整,粗糙度较低,具有宽广的钝化区,最大的极化电阻值,较小的致钝电流值和自腐蚀电流值,耐腐蚀性能最佳。

英文摘要：

Anodic oxide films on TA2 commercially pure titanium surface were prepared with sodium tartrate environmental solution by a potentiostatic method at the concentrations of 1, 5, 15, 30 and 50 g/L. The microstructure of the films was analyzed by atomic force microscope, the Tale1 polarization curves and electrochemical impedance spectra of the samples at low potential of 3.5% NaCI were analyzed by electrochemical workstation, and the influence of microstructure on corrosion resistance was discussed. The results show that when the concentration is about 15 g/L, the oxide film has a good micro morphology, a broad passivation area, a maximum polarization resistance value, smaller passivation current and self corrosion current, when it has the best corrosion resistance.
