Abstract Ti-Ta composite material has high specific strength, low modulus and good biocompatibility, and has potential applications in the fields of biomedicine and chemical industry. In this paper, a highly dense Ti-Ta composite material with a nominal composition of Ti-20%Ta (mole fraction) was prepared by spark plasma sintering and thermal deformation using Ti and Ta powders as raw materials. The microstructure of the material was analyzed and the surface state of the material was modified by surface sandblasting and alkali heat treatment. The results show that Ta particles are uniformly distributed in the Ti matrix, and the interface between Ta and Ti has an apparent compositional gradient, but the diffusional range is narrow. Compared to Ti-Ta composite material surfaces treated by sand blasting, those treated by sand blasting and alkali-heat treat mentexhibits enhanced cyto-compatibility. The reason for the improvement of biological properties of modified Ti-Ta composite material may be that the nano-pore structure formed on the surface is helpful for protein adsorption, and the sodium titanate and sodium tantalate formed on the surface have better adsorption properties for protein. Therefore, surface alkali-heat treatment is an effective way to improve the biocompatibility of Ti-Ta composite material.

Key words： Ti-Ta composite material sand blasting alkali-heat treatment microstructure surface modification cyto-compatibility
