| Abstract: | Co coated surface condition of cemented carbide will seriously effect the service performance. In this paper the effects of chemical erosion, addition agent and sintering atmosphere on the Co-coated surface condition of cemented carbide was studied. The results indicate that it is not easy to control the chemical erosion in production process; while by means of addition agent and sintering atmosphere the Co-coated surface condition of cemented carbide will be improved effectively. |
