Abstract

Co-based alloys (Co-212) have been used in biomedical application for implant materials  because of promising as a potential material for biomedical applications. This paper describes the effect of sintering conditions on microstructural, mechanical, and electrochemical properties of injection molded for Co-based superalloy. Co-212 powders were injection molded with wax-based binder. The critical powder loading for injection molding was 60 vol.%. Binder debinding was performed in solvent and thermal method under high purity argon atmosphere. After debinding, the samples were sintered at different temperatures and times in vacuum. The densities of the sintered components were determined in accordance with the Archimedes' principle. A correlation between sintering temperature and time which bring about high densification and good corrosion resistance was obtained. Results of study showed that injection molded Co-based alloys exhibited high mechanical and corrosion properties in a physiological environment. Maximum density and hardness were obtained for maximum sintering temperatures and times.
