利用非晶合金粉末在过冷液相区的超塑性和预制体盐的混合物在热挤压下制备了Zr55Cu30Al10Ni5多孔非晶合金。采用扫描电镜(SEM)、X射线衍射仪(XRD)、差示扫描量热仪(DSC)分析了合金的组织、相结构以及热稳定性。利用动态凝血时间以及溶血率分析了多孔非晶合金的血液相容性。结果表明,热压过程未出现晶化现象,多孔块体合金完全由非晶相组成,只有少于3.5%的残留盐密封在非晶合金中。动态凝血时间长达40min,溶血率为1.85%,这表明Zr55Cu30Al10Ni5多孔块体非晶合金具有良好的生物相容性。 Zr55Cu30Al10Ni5 porous amorphous alloy was prepared by hot extruding the mixture of superplastic and preform salt in the supercooled liquid region by using amorphous alloy powder. The microstructure, phase structure and thermal stability of the alloy were analyzed by SEM, XRD and DSC. The hemocompatibility of porous amorphous alloys was analyzed by dynamic coagulation time and hemolysis rate. The results show that no crystallization occurs during the hot pressing process. The porous block alloy consists entirely of amorphous phase, and only less than 3.5% of the residual salt is sealed in the amorphous alloy. Dynamic coagulation time up to 40min, hemolysis rate of 1.85%, indicating that the porous Zr55Cu30Al10Ni5 porous block has good biocompatibility.
