| 摘 要： | 利用渗流铸造法制备了直径为6mm的vit106非晶合金与羟基磷灰石(HA)的复合材料,分别采用扫描电镜(SEM)、X射线衍射(XRD)分析了铸态合金的组织形貌和相组成.实验结果表明,铸态合金由非晶组织和HA组成,二者均匀分布,界面结合良好.力学性能实验表明,复合材料的压缩断裂强度为250MPa,最大塑性变形量达到了65%.与目前钛合舷金/20%(体积分数)HA复合材料相比,强度得到了提高;与块体非晶合金多孔材料相比,在相近的强度指标下,具有更高的塑性.由于HA与非晶合金都具有良好的生物相容性,因此这种复合材料在生物移植材料上具有一定应用前景.

| Abstract: | A 6mm diameter composite with metallic glass matrix(Vit106) and Hydroxyapatite(HA),as second phase,was fabricated by using melt infiltration casting method.The structure and phase constituent were investigated by means of scanning electron microscopy(SEM) and X ray diffraction(XRD).The results show that the HA particles are distributed uniformally in the amorphous matrix with good bonding interfaces with the matrix.The mechanical tests show that the compossive strength up to 250MPa and maximal elogation up ... |
