摘要: 通过正交试验法，采用动电位扫描技术研究了温度、pH和Cl-浓度对NiTi形状记忆合金在模拟口腔溶液中电化学行为的影响.结果表明温度、pH和Cl-浓度对NiTi的点蚀行为都有较大影响.溶液温度为25 ℃时点蚀电位最负，随着温度的升高，点蚀电位逐渐升高.溶液中的Cl-浓度很低时(不超过0.1 mol/L)点蚀电位较高，随着Cl-浓度的增加，点蚀电位急剧下降.当溶液的pH为6.0时，点蚀电位最高.

Abstract：Potentiodynamic polarization measurement was used to study effects of temperature,Cl- concentration and pH on the electrochemical behavior of NiTi shape memory alloy (SMA)in the synthetic saliva according to the orthogonal testing method.The results showed that temperature,Cl- concentration and pH had great influence on the pitting behavior of NiTi.The breakdown potential was most negative at 25 ℃,and it increased with the increase of temperature.The breakdown potential kept in high level when the Cl- concentration was not more than 0.1 mol/L,while it dropped sharply with the continuous increase of Cl- concentration. The breakdown potential was highest at the solution of pH 6.0.

Key words： NiTi shape memory alloy potentiodynamic polarization measurement orthogonal testing method biocompa
