Graphene-coated tungsten carbide core-shell powder, preparation method thereof and application of graphene-coated tungsten carbide core-shell powder in composite ceramic cutter material
The invention provides graphene-coated tungsten carbide core-shell powder, a preparation method thereof and application of the graphene-coated tungsten carbide core-shell powder in a composite ceramic cutter material. The graphene-coated tungsten carbide core-shell powder is rapidly prepared in situ in one step by adopting a liquid-phase laser irradiation technology, the process is simple, the consumed time is short, the cost is low, and the preparation process is safe and environment-friendly. The graphene coated tungsten carbide core-shell powder has high dispersibility, the core-shell structure effectively improves the dispersion uniformity of graphene in a ceramic matrix material, and the disadvantages of harsh and complex process, non-uniform mechanical mixing, easy agglomeration and the like of independent preparation of graphene are avoided; the obtained graphene-coated tungsten carbide core-shell powder is applied to preparation of a ceramic cutter material and can be uniformly dispersed in a ceramic matrix material, and the obtained cutter material has excellent mechanical properties.
