Abstract

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.
