ABSTRACT

The Co-Cr as-cast alloys are widely used in the manufacturing of orthopedic implants made with investment casting techniques because of its high strength, good corrosion resistance and excellent biocompatibility properties. Carbide precipitation at grain boundaries and interdendritic regions is the major strenthening mechanism in the as-cast condition. In this study, effects of GPS (Gas Pressured Sintering) heat-treatment on the microstructure and crystallinity of the as-cast Co- Cr alloy prepared by investment casting were investigated. It was confirmed that the content of metal carbide (Cr23C6) was increased in the grain boundary by using optical microscopy (OM), field-emission scanning electron microscopy (FE-SEM) and energy dispersive spectroscopy (EDS).
