中文摘要:
      采用放电等离子烧结技术制备多孔Zn-Mg合金探讨了Mg含量对多孔合金孔隙特征和力学性能的影响,并分析了多孔Zn-Mg合金的断裂失效机制。结果表明,在造孔剂 (NaCl) 体积分数固定前提下当Mg含量从5 wt.%增加至15 wt.%,由于在去除造孔剂的过程中去合金化作用,孔隙率从40.3 %提升至54.3 %,表面开孔直径从289 μm增加到384 μm。力学测试结果表明,多孔Zn-Mg合金为一种弹脆性多孔材料;三种组分中多孔Zn-10Mg合金力学性能最好,其强度与弹性模量均能满足作为承受低载荷松质骨的需求。

英文摘要:
      In this study, porous Zn-xMg alloy scaffolds (x=5,10 and 15 wt.%) were fabricated as bone tissue engineering scaffold by spark plasma sintering (SPS) using same volume content space holder (NaCl). The effect of content of Mg on the mechanical properties, microstructural characterizations of the porous Zn-xMg alloys scaffold were revealed. Results showed that with increasing content of Mg, the porosity increased from 40.3% to 54.3% and the mean open pore size increased from 289 μm to 384 μm due to the dealloying effect of Mg. Mechanical tests results showed that porous Zn-Mg alloy was a typical elastic-brittle metallic foam and porous Zn-10Mg was best among three scaffolds. The strength and elastic module of the scaffolds showed good biomechanical compatibility and had the promising to be used as a lower load-bearing implant material.
