Mg-3 Nd-0.2Zn-0.4Zr合金是一种具有良好力学性能的新型可生物降解镁合金。为了改善在初始愈合阶段的表面稳定性,并促进组织生长的生物医学植入物由这种镁合金,氧等离子体浸没离子注入(O-PIII)进行改性的合金表面。虽然O-PIII增加了表面氧化物的厚度,但没有观察到表面耐腐蚀性的显著改善。因此,在O-PIII之前,通过高能离子注入进行Al和Cr的表面合金化。在模拟体液中获得的电化学数据,包括极化曲线和电化学阻抗谱(EIS),表明表面合金化后的表面耐腐蚀性提高。我们的研究结果表明,表面合金化与铬产生最好的结果,在这项研究中。这种改进源于在注入层中形成含Al或Cr的氧化膜。
Mg–3Nd–0.2Zn–0.4Zr alloy with good mechanical properties is a new type of biodegradable magnesium alloy. In order to improve the surface stability in the initial healing stage and foster tissue growth on biomedical implants made of this Mg alloy, oxygen plasma immersion ion implantation (O-PIII) is conducted to modify the alloy surface. Although O-PIII increases the thickness of the surface oxide, no significant improvement in the surface corrosion resistance is observed. Hence, surface alloying with Al and Cr by means of high-energy ion implantation is conducted prior to O-PIII. The electrochemical data obtained in simulated body fluids, including polarization curves and electrochemical impedance spectra (EIS), reveal that the surface corrosion resistance is improved after surface alloying. Our results show that surface alloying with Cr produces the best result in this study. The improvement stems from the formation of Al or Cr-containing oxide films in the implanted layer.
