| 摘 要： | 目的:研究在含氟模拟体液中纯钛表面微弧氧化膜的耐腐蚀性能。方法:制备纯钛试件,利用电化学方法测量纯钛表面微弧氧化处理后的极化曲线和交流阻抗。电化学实验溶液体系分为2组(n=4),分别为不含氟模拟体液组(A组)和加NaF模拟体液组(B组)。结果:和不含氟模拟体液组比较,含氟组中微弧氧化处理后试样的自腐蚀电位、自腐蚀电流密度增大和交流阻抗减少,差异均有显著性(P<0.01)。结论:氟离子可以降低纯钛微弧氧化后的耐腐蚀性能。

| Abstract: | Objective: To study the corrosion resistance of micro-arc oxidation film on titanium in F-containing simulated body fluid.Methods: Samples of pure titanium were prepared and treated in simulated body fluid group(A,n=4) and F-containing simulated body fluid group(B,n=4) respectively.Polarization curves and electrochemical impedance spectrum of the samples in the electrochemical test solutions were obtained by electrochemical methods.Results: The self-corrosion potential and self-corrosion current density of titanium samples treated in F-containing simulated body fluid was higher(P<0.01) and the electrochemical impedance was lower(P<0.01) than those treated in simulated body fluid.Conclusion: Fluoride ions may decrease the corrosion resistance of micro-arc oxidation film on titanium. |
