Metal alloys applied as biomedical materials have been developed for decade, due to the need for devices implanted into the human body. One of them is a cobalt-based alloy which commonly used as an orthopedic implant for total hip replacement. The biocompatibility properties of CoCrMo alloys make these alloys superior to corrosive resistance when making direct contact with the biological environment of the body where Simulated Body Fluid (SBF) solution is a solution often used to test its compatibility. The presence of manganese elements in CoCrMo Alloy and influence of heat treatment at temperature 700 oC for 65 hours were characterized by using X ray diffraction and Potentiostat. The structure and corrosion behavior in Simulated Body Fluid were discussed. The results show different crystal parameter and corrosion behavior observed. It concludes that, heat treatment and the presence of Mn affect the signicantly on the properties of CoCrMo Alloy.
