Biomedical materials: A review of titanium based alloys

Abstract

The sterling mechanical properties of titanium alloys have distinguished them as an essential material for varied applications especially in biomedical fields. The combination of good corrosion resistance in addition to light weight, non-toxicity and an outstanding biocompatibility makes them a sought-after material for production of medical implants. Owing to the surging demand for durable implants, it has become exigent for increased developmental researches on biomaterials to be accelerated. This will result in significant increase in implant production and Ti alloys will play a vital role among the several materials presently in use. Hence, this review critically analysed the important roles Ti alloys have played thus far in the implant production industry and recent development of titanium-based alloys with low elastic modulus similar to human bones as well as improved biocompatibility and wear resistance.
