中文摘要:
      采用真空吸铸法通过将Mg-3Zn合金渗透到HA含量不同的多孔HA+β-TCP中制备了生物医用相互渗透(HA+β-TCP)/Mg-3Zn复合材料,研究了复合材料的显微组织、力学性能和腐蚀行为。研究结果表明,熔融的Mg-3Zn合金不仅渗入到多孔HA+β-TCP骨架的孔隙里,也渗入到筋里,形成了致密的复合材料。Mg-3Zn合金与HA+β-TCP骨架界面结合良好,未发现反应层。HA含量不同的(HA+β-TCP)/Mg-3Zn复合材料的压缩强度为115 ~196 MPa,是多孔HA+β-TCP骨架的350倍以上,相当于Mg-3Zn块体合金强度的44 %~75 %,复合材料的耐腐蚀性能优于Mg-3Zn块体合金的,且机械性能和腐蚀行为均可以通过调节HA/β-TCP的比例进行控制。

英文摘要:
      The interpenetrating (HA+β-TCP)/Mg-3Zn composites were fabricated by infiltrating Mg-3Zn alloy into porous HA+β-TCP with different HA content using suction casting technique, the microstructure, mechanical properties and corrosion behaviors of the composites have been evaluated. It presented that the molten Mg-3Zn alloy had infiltrated not only into the pores but also into the struts of the porous HA+β-TCP scaffold to forming a compact composite. The Mg-3Zn alloy contacted to the HA+β-TCP scaffold closely, and no reaction layer can be found. The compressive strength of the (HA+β-TCP)/Mg-3Zn composite with different HA content were 115~196 MPa, which were about 350-fold higher than that of the original porous HA+β-TCP scaffold and 44 %-75 % of the strength of the Mg-3Zn bulk alloy. The corrosion resistance of the composites was better than that of the Mg-3Zn bulk alloy, and the mechanical and corrosive behavior of the composites were controled by the choice of HA /β-TCp ratio.
