The Effect of Manganese and Heat treatment on Structure and Corrosion Resistance of Cobalt Chrome Molybdenum

Abstract

The selection of implant biomaterials must be based on the compatibility of the human body so that it has significant properties that will last long without experiencing rejection during use in the body. One of the commonly used for biomedical implants is Co-Cr-Mo alloy. Since these alloy should also fulfill implant requirements such as high corrosion resistance. To increase corrosion resistance, the heat treatment temperature and time (heat treatment parameters) were 65 hours at 700 °C. Characterization was performed using X-ray diffraction and Potensio dynamic. The different X-ray diffraction patterns and corrosion resistance were obtained. The results show both structure and corrosion resistance are markedly influenced by the addition of Manganese after heat treatment.
