不同状态下稀土镁合金的生物相容性能研究
Biocompatibility of Rare Earth-magnesium Alloy Mg-RE-Zn in Different States
传统医用镁合金材料有诸多缺点，比如含有有害元素以及较差的耐蚀性能。本文采用了了电化学测试、浸泡测试以及力学性能测试研究了不同状态下稀土镁合金Mg-4Gd-0.3Zn的生物相容性能。XRD的测试结果表面该成分的稀土镁合金及其腐蚀产物不含毒性。实验结果显示挤压态的Mg-4Gd-0.3Zn合金比铸态和固溶态具有更加细小均匀的晶粒组织，同时具有更好的耐蚀性能和力学性能，将来应用于人体植入材料具有良好的前景。
raditional magnesium alloys for the purpose of medical implant materials have disadvantages such as containing harmful alloying element and poor corrosion resistance. Electrochemical measurement, immersion test and mechanical property test have been performed in this paper to study the biocompatibility of ternary rare earth magnesium alloy Mg-4Gd-0.3Zn in different states. The as-extruded Mg-4Gd-0.3Zn alloy with non-toxic composition of corrosion products, better corrosion resistance and mechanical properties comparatively will be a promising biocompatible medical material in future.
