Abstract: Materials play an important role in the development of product for many applications. Biomaterials are the class of materials abundantly used as dental implants, orthopedic implants, tissue replacements, supports, replacement of joints in human body parts like HIP, Knee etc in biomedical field. Biomaterials are biocompatible which are having an appropriate response with the host for a specific application. As these members are prone to physiological conditions in the human body, they tend to fail because aseptic loosening caused by the per prostheticosteolysis. The studies shown that the cause for the osteolysis is wearing debris of biomaterials.In order to improve the tribiological characteristics like corrosion and wear, to increase the life span of these biomaterials, their surface is to be modified. In this work an attempt has been made to improve the tribological characteristics by modifying the surface through thin film coatings. Tests are performed to know the behavior of modified biomaterials and also a comparison is made between the coated and uncoated materials . It is observed that there is a significance improvement in corrosion and wear of coated Mg alloy compared to uncoated Mg alloy. I.
