Research on the Development of WC-Ni Cemented Carbides
The material of solid ring with appropriate and consistent strength, stiffness, wear-resistance and thermal conductivity will allow for the maintenance of mechanical seal working normally. Properties of physical and mechanical of WC-Ni cemented carbides and current research situation are surveyed in the present paper. The application and research on mechanical face seals are also briefly introduced. The effects of microstructure of WC grain and binders as well as the external stress on cemented carbides were described. The further research of WC-Ni cemented carbides used on mechanical face material has proposed according to the material characteristics and under the current research progress to meet the requirement of practical application.
