J Mater Sci Mater Med:多孔钛支架在整形外科植入物中的应用潜力

2019-10-29 不详 网络

定制的多孔钛合金已成为骨科植入物应用的新兴材料。在这项工作中,研究人员通过选择性激光熔化(SLM)制备了菱形和菱形十二面体多孔Ti-33Nb-4Sn支架。系统地研究了相,微观结构和缺陷特征,并将其与孔结构,晶胞尺寸和加工参数对支架机械性能的影响相关。由于SLM工艺中的快速凝固速度,在Ti-33Nb-4Sn支架中获得了精细的β相树枝状晶体。支架的抗压强度和抗弯强度随支柱尺寸的减小而降低,金刚石结构的

定制的多孔钛合金已成为骨科植入物应用的新兴材料。在这项工作中,研究人员通过选择性激光熔化(SLM)制备了菱形和菱形十二面体多孔Ti-33Nb-4Sn支架。系统地研究了相,微观结构和缺陷特征,并将其与孔结构,晶胞尺寸和加工参数对支架机械性能的影响相关。

由于SLM工艺中的快速凝固速度,在Ti-33Nb-4Sn支架中获得了精细的β相树枝状晶体。支架的抗压强度和抗弯强度随支柱尺寸的减小而降低,金刚石结构的抗压强度和抗弯强度均高于十二面体结构。

通过SLM获得的金刚石Ti-33Nb-4Sn支架的抗压强度为76 MPa,弯曲强度为127 MPa,弹性模量为2.3 GPa,揭示了Ti-33Nb-4Sn支架在整形外科植入物中的应用潜力。
