    Dry Sliding Wear Behavior of Al2O3-TiO2 Coated Ti6Al4V Alloy based on Taguchi Method

    By M. Raja Roy, Ramanaiah N, Sundara Siva Rao B. S. K

    Abstract: AbstractTi6Al4V alloys are extensively used as implant material for bio-medical applications due to their high specific strength. But, their poor wear resistance results in formation of wear debris in implants and causing soreness. In this work, Al2O3-TiO2 coatings were applied to improve the wear resistance and hardness. Al2O3-TiO2 coatings are deposited on the substrate with 100, 200, 300, 400 µm thickness using detonation spray (DS). Pin on disc wear tests …

    Mechanical and Tribological Properties of Cr3C2-NiCr Coated Ti6Al4V Implant Alloy

    By M. Raja Roy, N. Ramanaiah, B.S.K. Sundara Siva Rao, M. Srinivasa Rao

    Abstract: Ti6Al4V alloys are widely used in medical and aerospace applications due to their superior mechanical properties. But, Ti6Al4V alloys are poor in tribological properties such as wear. Poor wear resistance consequences in the formation of wear debris in human implants and leads to inflammation and pain. In this work, Cr3C2-NiCr coatings were applied to improve the mechanical properties such as tensile strength, hardness and tribological properties such as wear resistance. …
