Influence of Mangan on Structure and Corrosion Properties of Cobalt Chrome Molybdenum (Co-Cr-Mo)

Co-Cr-Mo alloy are usually used as implant materials in biomedical application. Corrosion resistance is one of the properties needed to full fill the requirement. The nature of material resistance in the body (biocompatibility) is determined by the corrosion resistance of a biomaterial. Corrosion which emits metal ions in the tissue directed at the implant and activates the system in the body. Mangan (Mn) were added to this alloy to enhance corrosion resistance. Addition of Mangan (Mn) might also affect to the structure of this alloy. X ray diffraction and Electrochemical experiment were conducted to characterized the structure and corrosion resistance of this alloy. The addition of Manganase shows significant influence on the structure and corrosion resistance on the Co-Cr-Mo alloy.
