摘要
There is disclosed a method of making a metallic or ceramic component, such as a cutting or forming tool, from at least two distinct powder precursors. In one embodiment, the method comprising forming a first mixture comprised of a plurality of coated particles, such as Tough-Coated Hard Powder (TCHP) composite particles created by encapsulating extremely hard core particles with very tough binder and structural materials, and at least one support powder, such as a carbide, typically WCCo. The mixture is formed into a green body and sintered to form a functionally graded or multicomponent article. Non-limiting examples of the articles made from the disclosed methods are also disclosed and include drills, mills, cutting tools, forming tools, wires dies and mechanical components.
