Abstract:
1. A method of fabricating a polycrystalline diamond compact, comprising: fabricating a polycrystalline diamond element in a high-pressure/high-temperature process including subjecting a cell assembly including a pressure transmitting medium at least partially enclosing diamond particles and a metal-solvent catalyst to a temperature of at least about 1000° C. and a pressure in the pressure transmitting medium of at least about 7.5 GPa, the polycrystalline diamond element including: wherein the polycrystalline diamond element exhibits a G removing at least a portion of the metal-solvent catalyst from the polycrystalline diamond element; and brazing the polycrystalline diamond element to a substrate to form the polycrystalline diamond compact.
