摘要

摘要: 利用放电等离子烧结(SPS)制备了Ti/HA复合材料,研究了不同配比的Ti/HA复合材料的显微组织、致密度及pH值,并进行了生物溶血试验。结果表明:经颗粒表面钝化处理后,50％Ti-50％HA复合材料的相对密度由73％提高到94.4％,pH值保持中性,溶血试验指标为4%,符合生物材料的应用要求。

Abstract: Ti/HA composites were manufactured by spark plasma sintering (SPS). The microstructure,density and the pH value were studied for Ti/HA samples with different proportions. The biological hemolytic experiment was done. The result indicates that the relative density of 50％Ti-50％HA composite increases from 73％ to 94.4％ while the particles are passivated before sintering, the pH value remains neutral and the biological hemolytic experiment index is 4%, which meets the demand of bioactivity materials.
