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 superabrasive compact and a method of making the superabrasive compact are disclosed. A method of making a superabrasive compact may comprise steps of treating a substrate to remove a first binder material from a portion of the substrate; introducing a first material into the portion of the substrate, forming a first modified substrate; and treating the porting of modified substrate to remove at least a part of the first material to form a second modified substrate.
