可降解医用镁合金耐腐蚀性能研究进展

Research Progress of Corrosion Resistance of Degradable Medical Magnesium Alloys

本文针对可降解吸收的医用镁合金的耐腐蚀性较差、在临床上的应用受到了很大的限制的问题,介绍了3种典型医用镁合金耐腐蚀性能的变化和近几年有关可降解医用镁合金的腐蚀研究进展,总结了研究可降解医用镁合金耐腐蚀性能的实验方法和结果。结论是未来医用镁合金既要充分发挥其可降解吸收的优点,又要把控好在人体服役期间的降解速度。

Due to the poor corrosion resistance of the degradable and absorbable medical magnesium alloy, its clinical application is greatly restricted. This article reviews the corrosion resistance of three typical medical magnesium alloys and the research progress on the corrosion of degradable medical magnesium alloys. This article also summarizes the experimental methods on the corrosion resistance of degradable medical magnesium alloys. Regarding future research on medical magnesium alloys, it is necessary to give full play to its advantages of degradable absorption, but also to control the degradation rate during human service.
