N2 - The Ti-XSn (X = 5, 10, 15) (wt.%) alloys are fabricated by mixing TiH2/Sn powders, then compacting and extruding. The microstructure, mechanical properties, and biocorrosion resistivity of the Ti-XSn rods are studied and compared with the CP Ti fabricated with the same condition by the powder compact extrusion of TiH2. The Ti-XSn alloys exhibit significantly high tensile strength, hardness, and low elongation with increasing Sn content. The strength of the Ti-XSn alloys is increased from 648 to 801 MPa, and the elongation is reduced from 11.4 to 5.3%, with the Sn content increasing from 5 to 15 wt.%. The biocorrosion resistance of the Ti-XSn alloys is higher than the CP Ti. With increasing Sn content, the polarization resistance of the Ti-XSn alloys increases due to the reduced availability of corrosive ions on the surface. The Ti-XSn alloys generally revealed excellent biocorrosion resistivity and tensile strength compared to the CP Ti.
