Abstract
For decades, titanium (Ti) and its alloys have been used in industrial applications such as automotive, aerospace, and petrochemical because of its high corrosion resistance and mechanical properties. Recently, Ti-alloys are widely used in biomedical applications such as orthopedic, orthodontic, pacemakers, bone plates, artificial knee joints, hip joints, and screws for fracture fixation. Similar to other biomaterials such as Co–Cr–Mo alloy and SUS316L stainless steel, Ti-alloys provide a proper combination of biological compatibility and excellent mechanical properties. Among the most used Ti-alloys in medical application. Ti-15Mo-2Si as-cast alloy exhibited the highest dry and wet wear resistance of all studied Ti-15Mo-xSi alloys. Worn surfaces of some selected wear samples after wear test were also examined. Moreover, corrosion behavior of Ti-15Mo-2Si alloys showed a corrosion rate of 0.001256 mm/year, which is considered the best among all tested Ti-alloys.
