Abstract
Mo and Nb elements have been considered as β-stabilizer and non-toxic elements in Ti alloy. Therefore, Ti–17 wt-%Mo–10 wt-%Nb alloy was used to reduce the Young’s modulus and improve the biocompatibility in this study. In addition, spark plasma sintering was used for consolidation of Ti–17Mo–10Nb milled powders by high-energy mechanical milling during 1–8 hours. Consequently, the compression strength, Young’s modulus and biocompatibility could be improved by proper milling time of Ti–17Mo–10Nb powder. To investigate the microstructure, phases and mechanical properties of Ti–17Mo–10Nb alloy, scanning electron microscope, X-ray diffraction and compression test were conducted. Also the biocompatibility and corrosion resistant of this alloy was conducted by MTT (tetrazolium-based colorimetric) assay and polarization measurement, respectively. The results showed that biocompatibility of this alloy was improved by increasing milling time and Young’s modulus of Ti–17Mo–10Nb alloy decreased by using 8 hours milled powder.
