| 摘 要： | 在PBS溶液(pH=7.4)中采用电化学测试技术考察了免疫球蛋白G(IgG)与透明质酸(HA)对潜在的人工关节用TZNT合金腐蚀行为的影响。结果表明:免疫球蛋白G的吸附可在一定程度上减缓TZNT合金表面氧化膜的生长;透明质酸抑制TZNT合金腐蚀的效果与其掺入浓度和浸泡时间相关,在其浓度为2.5 g/L,浸泡72 h时,抑制合金腐蚀的效果最佳。

| Abstract: | The effect of Immunoglobulin G (IgG) and Sodium Hyaluronat (HA) on the corrosion behavior of TZNT alloy, as a type of potential artificial joint materials, has been investigated in PBS solution (pH=7.4) through electrochemical tests. The results show that the growth of the surface oxide film on TZNT alloy in PBS can be inhibited by the addition of IgG to some extent. HA is effective to decrease the corrosion rate of TZNT alloy, and it is influenced by the concentration and immersion period, and the best inhibitive effect can be obtained when the samples is exposed in test solution including 2.5 g/L HA after 72 h immersion. |
