▎ 摘　　要

NOVELTY - Preparation of modified graphene-containing tungsten carbide self-lubricating antifriction coating powder involves weighing modified graphene/nano tungsten carbide composite material, obtaining graphene/nano tungsten carbide composite material mixed solution, and distributing absolute ethyl alcohol; weighing tungsten carbide/cobalt spraying powder in mixed solution of graphene nano tungsten carbide composite material, and stirring at normal temperature to obtain mixed solution of modified graphene/nano tungsten carbide composite material and tungsten carbide/cobalt; and vacuum freezing. USE - Method for preparing modified graphene-containing tungsten carbide self-lubricating antifriction coating powder (claimed). ADVANTAGE - The method keeps laminated single layer carbon structure characteristic of graphene, improves proportion of graphene, and avoids loss of graphene.
