The invention discloses a boron-containing gradient cemented carbide with a shell structure and a preparation method thereof. The method is to perform boronizing heat treatment on a sintered dense cemented carbide matrix in a boron-containing filler, and the temperature of the heat treatment is slightly lower than that of the hard alloy. The liquidus point of the alloy matrix. The boron-containing gradient cemented carbide has a three-layer structure of surface layer, subsurface layer and core; the surface layer is a shell structure with a uniform distribution of boron-containing phases, the subsurface layer is a gradient transition structure with uniform changes in boron-containing phases, and the core is a structure that does not contain Boron-containing cemented carbide structure; and the concentration of boron-containing phase gradually decreases from the interface between the surface layer and the subsurface layer inwards, and completely disappears at the interface between the subsurface layer and the core. The service performance of the boron-containing gradient cemented carbide is obviously higher than that of ordinary cemented carbide, and the existence of the gradient layer avoids sudden failure caused by the performance difference between the boronizing shell layer and the alloy matrix.
