摘要: A polycrystalline diamond compact cutter that includes a thermally stable polycrystalline diamond layer, a carbide substrate, and a polycrystalline cubic boron nitride layer interposed between the thermally stable polycrystalline diamond layer and the carbide substrate is disclosed. A method of forming a polycrystalline diamond compact cutter that includes the steps of providing a carbide substrate, disposing a polycrystalline cubic boron nitride layer on the carbide substrate, disposing a polycrystalline diamond layer on the polycrystalline cubic boron nitride layer, and treating at least a portion of the polycrystalline diamond layer to form a thermally stable polycrystalline diamond layer is also disclosed.
