镁基非晶合金作为生物材料的应用现状

Present Situation of Amorphous Mg-based Alloy as Biological Materials

镁合金由于其密度小,比强度高等特点愈发受到社会关注,其非晶合金又由于弥补了传统晶态镁合金的部分缺点而成为当今研究热点之一。结合国内外文献及镁合金在国内外生物领域中的应用的具体情况,综述了传统镁合金在生物领域的应用现状,比较了镁基非晶合金与传统晶态镁合金的腐蚀情况,探究了镁基非晶合金因其非晶性能而得到的更优的力学性能,展望了镁基非晶合金作为生物材料的发展前景,为镁基非晶合金在生物材料领域中的应用技术研究及发展提供参考。

Mg alloy is gradually used due to its low density as well as high specific strength.Its amorphous alloy also becomes the focus of research as supplement of traditional crystalline Mg alloy.Combined with domestic and foreign researches,the present situation of traditional crystalline Mg alloy used in biology area is reviewed,such as its cure of bones deficiency and its drawback of being easily corroded.Different corrosion situations of amorphous Mg-based alloy and traditional crystalline Mg alloy are compared.The better mechanical properties of amorphous Mg-based alloy are researched as well.The future of amorphous Mg-based alloy as biological material are predicted,so as to provide some references and views for application research and development of amorphous Mg-based alloy in the field of biology.
