可降解生物医用镁合金材料的研究进展

Research Progress of Degradable Biomedical Magnesium Alloy Materials

生物医用材料因其在现代医学领域的许多重要应用而引起了越来越多的学者的兴趣。其中,镁合金由于具有优异的生物相容性和力学性能而在众多材料中脱颖而出,成为潜力非凡的可降解金属骨移植材料。但是其在生物体内降解速率过快,严重限制了其实际应用。针对这一问题,本文概述了镁合金的合金化、表面处理、非晶化和复合材料等四类减缓其降解速度的研究现状,并提出展望,以期对生物医用镁合金的实际应用提供参考。

Biomedical materials have attracted more and more scholars＇ interest due to their many important applications in the field of modern medicine.Among them,magnesium alloy stands out among many materials due to its excellent biocompatibility and mechanical properties,becoming a degradable metal bone graft material with extraordinary potential.However,its degradation rate in organisms is too fast,which severely limits its practical application.In view of this problem,this paper summarizes the status of four types of research which can slow down the degradation rate of magnesium alloy,including alloying,surface treatment,amorphous and composite materials,and puts forward the prospect,hoping to provide a reference for the practical application of biomedical magnesium alloy.
