Abstract: A cutting element include a substrate and a diamond compact including at least two polycrystalline diamond portions separated by at least one metal carbide foil portion. The cutting element is made by placing diamond powder in a reaction container, placing a thin metal layer in the reaction container above or around the diamond powder and binder, placing additional diamond powder in the reaction container above or around the thin metal layer, and placing a pre-sintered substrate containing binder into the reaction container above all diamond powder and thin metal layer components. The assembled reaction container is put into a reactor and is subjected to a high-temperature high-pressure sintering process. The binder in the pre-sintered substrate sweeps through to sinter the first diamond portion, and then reacts with the thin metal layer to form a metal carbide, and then the binder continues to sweep through to sinter the second diamond portion.

Abstract: A polycrystalline diamond compact made from a high pressure, high temperature process is provided. The compact includes a metal carbide substrate including a binder and at least one inner layer of polycrystalline diamond disposed on the substrate. The polycrystalline diamond has a diamond phase and a metal phase forming an interconnected mutually exclusive network. The metal phase is a material different than that of the binder of the substrate to provide improved diamond sintering and final polycrystalline diamond compact properties. Prior to processing at least one coating is disposed on the substrate, and the layer of diamond particles is disposed on the at least one coating. During the high pressure, high temperature process the coating melts and fully sweeps into the diamond layer.
