Abstract: A method of making a near-net superhard material body includes preparing granules from a mixture of superhard powder, binders, and fluids, compacting the granules to form a soft green complex-shaped body, heating the soft green body in a furnace to form a hard green body free from residual binders, embedding one or more of the hard green bodies in a containment powder or a containment means and forming a pressure cell, sintering the cell at high pressure and high temperature, and removing the containment powder from the cell or removing the inserts from the containment means to reveal one or more near-net bodies.

Abstract: A sintered cutting element including a superabrasive layer supported on a substrate. The superabrasive layer includes superabrasive material and secondary phase, and the substrate includes a binder phase. The sintered cutting element is formed by a high temperature high pressure sintering process in which separate source elements melt and sweep first through the superabrasive layer, and then to the substrate to form the secondary phase and binder phase. The superabrasive layer is substantially free of or free of eta-phase, Co 3 W 3 C. Further, the portion of the substrate nearest the interface between the superabrasive layer and the substrate has equal or more binder phase than portions of the substrate further from the interface. In certain embodiments, the superabrasive material includes polycrystalline diamond, and the substrate includes cobalt tungsten carbide.
