| titleOfInvention | A method and system for improving the performance of shield cutting tool carbide |
| abstract | The invention belongs to the technical field of alloys, and discloses a method and a system for improving the performance of a shield cutting tool cemented carbide. Co powder is mixed, and then through ball milling, drying, and sintering processes in sequence to obtain a shield cutting tool cemented carbide. The graphene of the present invention utilizes ultrasonic vibration dispersion in an organic solvent, and is ball-milled with the cemented carbide raw material powder for a long time, so that a good mixing effect can be achieved, so as to achieve uniform organization in the subsequent sintering process and reduce sintering defects; Graphene has excellent thermal conductivity and comprehensive mechanical properties, which can improve the thermal conductivity and mechanical properties of cemented carbide. |
