    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。

    Abstract:

    Anodic oxide films on TA2 commercially pure titanium surface were prepared with sodium tartrate environmental solution by 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 Tafel polarization curves and electrochemical impedance spectra of the samples at low potential of 3.5% NaCl were analyzed by electrochemical workstation, and the influence of microstructure on corrosion resistance wsa discussed. The results show that when the concentration is about 15 g/L, the oxide film has a good micro morphology, broad passivation area, maximum polarization resistance value, smaller passivation current and self corrosion current, is the best process conditions.
