Abstract
The as-cast Co–Cr–Mo alloy (ASTM F75) has been widely used as biomaterial in orthopaedic implant because of its excellent mechanical properties, good corrosion resistance and biocompatibility. However, some defects such as porosity and pinhole in an as-cast make some problems for application. Therefore in this study, the cobalt-aluminate (CoAl2O4) used as an inoculant during coating plays to refine the grain size and to reduce the porosity and pinhole content in an as-cast. Therefore, the effect of an inoculant addition on defect content, microstructure and mechanical properties of as-cast Co–Cr–Mo alloy has been investigated. The mechanical properties of the Co–Cr–Mo alloy were improved by addition of an inoculant.
