Harmonic reducer composite ceramic bearing and preparation method thereof
The invention relates to a harmonic reducer composite ceramic bearing and a preparation method thereof, which are used for solving the problems of poor flowability, difficult molding, low biscuit strength and poor high-temperature performance of a silicon-based ceramic core in the prior art. The invention provides a ceramic core material which is good in fluidity, high in molding rate and high inbiscuit strength and high-temperature strength, and a graphene material with excellent mechanical properties and thermal properties is introduced into a ceramic core material system. The graphene material enhances the flowability of the ceramic core slurry, the molding rate of the ceramic core, the strength of a green body and the high-temperature strength of the ceramic core. Besides, the ceramiccore disclosed by the invention is relatively high in pressing qualification rate and sintering qualification rate, high in impact resistance and excellent in high-temperature deformation resistanceand high-temperature strength.
