Durable bio-implants that can withstand the rigors of the physiological environment and applied mechanical stresses are of continuing interest to the biomaterials community. Titanium alloys are preferred candidates for structural implants. In this talk, we will discuss a new class of titanium alloys with boron additions that significantly increase the specific strength of the base alloys. The effect of boron on mechanical properties and the corrosion behavior of these alloys will be discussed. Open circuit potential and cyclic polarization measurements to determine the corrosion resistance of Ti-6Al-4V-B and Ti-B alloys in 0.9 wt% sodium chloride (saline) solutions will be presented. A mechanism for the corrosion behavior will be discussed and the role of the titanium boride, TiB, phase pointed out. Immune response studies for this system will be touched upon as well.
