ABSTRACT:
Metal carbide supported polycrystalline diamond (PCD) compacts having improved shear strength and impact resistance properties, and a method for making the same under high temperature/high pressure (HT/HP) processing conditions. A sintered polycrystalline cubic boron nitrite (PCBN) compact interlayer is provided to be bonded at a first interface to a sintered PCD compact layer, and at a second interface to a cemented metal carbide support layer comprising particles of a metal carbide in a binder metal. The supported compact is characterized as having a substantially uniform sweep through of the binder metal from the cemented metal carbide support layer, which sweep through bonds the sintered PCD compact layer to the sintered PCBN interlayer, and the sintered PCBN interlayer to the cemented metal carbide support layer.
