| titleOfInvention | A kind of preparation method of steel-based MoFeB cermet screw |
| abstract | The invention discloses a preparation method of a steel-based MoFeB cermet screw, comprising the following steps: machining a medium carbon quenched and tempered alloy into a steel-based screw core rod, and preparing Mo-Fe-B metal powder; The rod is placed in a cylindrical mold, the Mo-Fe-B metal powder is filled in the cavity between the steel-based mandrel and the cylindrical mold, and the composite body is obtained by vibrating, exhausting and sealing; cold isostatic pressing pressure Molding to prepare a steel-based Mo-Fe-B metal screw blank; mechanical roughing to process a screw blank; vacuum sintering to make a steel-based MoFeB cermet screw; finishing to make a finished screw. The steel-based MoFeB cermet screw of the invention has both super high corrosion resistance and wear resistance, excellent comprehensive performance, and can be widely used in the mixing and extrusion of halogen-free plastics, fiber-reinforced plastics, and metal powder-reinforced plastics. Plastic, injection screw. |
