Development of Degradable Mg-RE Based Biomaterials

摘要：

　　Mg alloy was increasingly attracting attention as a potential implant biomaterials for that there will be no need for a second surgery.However,the majority of conventional Mg alloys have been developed for automotive components and were not suitable for Mg based implants.In this paper,a new Mg-RE based material was developed for implant biomaterials,avoiding the negative influences of previous systems.Microstructure,mechanical and corrosion properties were investigated.The result exhibited that the mechanical properties and degradable rate were sufficient to satisfy the requirement of Mg-based implants.Furthermore,the deformability of the alloy was also investigated.The fine stent pipe was prepared by cold-drawing technology.The primitive results demonstrated that this new alloy was an ideal stent material.
