Graphene reinforced alumina-based ceramic bearing for robot
The invention relates to a graphene reinforced alumina-based ceramic bearing for a robot, which is prepared by the following steps: mixing alumina ceramic powder and graphene powder by using a three-dimensional mixer to obtain uniformly mixed alumina-based ceramic core powder; mixing the ceramic powder and a plasticizer to prepare required ceramic slurry, pressing a wet ceramic core sample by using a hot-press injection molding method, and sintering the obtained wet ceramic core under the protection of an inert atmosphere to obtain the graphene-reinforced alumina-based ceramic core. Accordingto the invention, the graphene material with excellent mechanical properties and thermal properties is innovatively introduced into the alumina-based ceramic core material system, the preparation process of the graphene-reinforced alumina-based ceramic core material is simple and feasible, the operability is strong, and the prepared ceramic core has excellent high-temperature properties and is easy to dissolve. The ceramic core can meet the preparation and use requirements of the single crystal hollow blade, and the size precision and the percent of pass of the blade can be guaranteed.
