Ti6Al4V alloys are extensively used in medical applications due to their superior mechanical properties. But, Ti6Al4V alloys are poor in tribological properties such as wear and corrosion resistance. Poor wear resistance leads to formation of wear debris in human implants and causes inflammation. In this work, Al2O3-TiO2 coating is applied to improve the wear and corrosion resistance. Al2O3-TiO2 coating was deposited on the substrate with 100µm, 200µm , 300µm , 400µm thickness using detonation spray(DS). Implants are lies inside the human body; Hence wear, surface roughness and corrosion behavior was studied in the simulated body environment using Hank’s solution. ASTM G-99 standard specimens are used for pin on disc wear tests. Experiments are carried out using Taguchi design. Grey relational analysis and response surface method are used for obtaining optimal experimental parameters. Improvement was observed in wear resistance for the Al2O3-TiO2 coated Ti6Al4V alloy.
