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。
The effect of immunoglobulin G (IgG) and hyaluronic acid (HA) on the corrosion behavior of TZNT alloy for artificial joint was investigated by electrochemical test in PBS solution (pH = 7.4). The results showed that the adsorption of immunoglobulin G slowed down the growth of the oxide film on the surface of TZNT alloy to a certain extent. The effect of hyaluronic acid on the corrosion inhibition of TZNT alloy was related to its concentration and immersion time. When its concentration was 2.5 g / L, When soaked for 72 h, the effect of inhibiting alloy corrosion is the best.
