摘要： A composite material includes a double cemented carbide and a coarse grain dopant, wherein the coarse grain is added in an amount sufficient to improve wear resistance of virgin double cemented carbide. The double cemented carbide may selected from the group of carbides consisting of W, Ti, Mo, Nb, V, Hf, Ta, and Cr carbides. The coarse grain dopant may also be at least one carbide selected from the group consisting of W, Ti, Mo, Nb, V, Hf, Ta, and Cr carbides. The coarse grain carbide may be between about 5% to about 90% by weight of the total carbide in the composite. Preferably, the coarse grain carbide is about 10% to about 50% by weight of the total carbide in the composite.
