Abstract: In an embodiment, a method of fabricating a polycrystalline diamond compact is disclosed. The method includes sintering a plurality of diamond particles in the presence of a metal-solvent catalyst to form a polycrystalline diamond body; leaching the polycrystalline diamond body to at least partially remove the metal-solvent catalyst therefrom, thereby forming an at least partially leached polycrystalline diamond body; and subjecting an assembly of the at least partially leached polycrystalline diamond body and a cemented carbide substrate to a high-pressure/high-temperature process at a pressure to infiltrate the at least partially leached polycrystalline diamond body with an infiltrant. The pressure of the high-pressure/high-temperature process is less than that employed in the act of sintering of the plurality of diamond particles.

Abstract: Embodiments relate to polycrystalline diamond compacts (“PDCs”), methods of fabricating PDCs, and applications for such PDCs. In an embodiment, a method includes providing an at least partially leached polycrystalline diamond (“PCD”) body. A residual amount of acid may remain in and/or on the at least partially leached PCD body. The method further includes removing and/or neutralizing at least some of the residual amount of acid from the at least partially leached PCD body and/or a substrate to which the at least partially leached PCD body is attached.

Abstract: Embodiments of methods are disclosed for characterizing a tested superabrasive element, such as a polycrystalline diamond element. In an embodiment, a method of characterizing the relative strength of a superabrasive element is disclosed. A first superabrasive element and a second superabrasive element are positioned upper surface to upper surface, including an area of overlap between the upper surfaces. A load is applied while the first and second superabrasive elements are overlapped until failure of one or both of the first or second superabrasive elements fail. A relative strength is determined using at least the load during failure as a parameter.

Abstract: Embodiments disclosed herein relate to cell assemblies for fabricating superhard materials (e.g., used in a high-pressure cubic press) and methods of using the same. The disclosed cell assemblies include a plurality of internal anvils, at least some of which are positioned internally relative to a cell pressure medium of the cell assembly. Such a configuration for the cell assemblies may enable one or more of intensifying cell pressure, reducing processing time, or reducing costs for fabricating such superhard materials.
