    摘要： Embodiments relate to PDCs, methods of fabricating PDCs, and applications for such PDCs. In an embodiment, a PDC includes a substrate and a pre-sintered PCD table including an interfacial surface that is bonded to the substrate. The pre-sintered PCD table may be substantially free of leaching by-products in a region at least proximate to the interfacial surface. In an embodiment, a method of fabricating a PDC includes providing an at least partially leached PCD including an interfacial surface. The method includes removing at least some leaching by-products from the at least partially leached PCD table. After removing the at least some leaching by-products, the method includes bonding the interfacial surface of the at least partially leached PCD table to a substrate to form a PDC.

    摘要： Embodiments relate to methods of fabricating polycrystalline diamond compacts (“PDCs”) in which a removing agent includes at least one supercritical fluid component that is used to remove at least one interstitial constituent from at least a portion of a polycrystalline diamond (“PCD”) body and applications for such PDCs. Removing the at least one interstitial constituent using the removing agent including the at least one supercritical fluid component may provide more rapid and effective removal of the at least one interstitial constituent from a PCD body than conventional acid leaching. In an embodiment, a method of fabricating at least partially porous PCD body includes providing a PCD body in which at least one interstitial constituent is disposed throughout, and removing at least a portion of the at least one interstitial constituent from the PCD body with a removing agent including at least one supercritical fluid component.

    摘要： In an embodiment, a polycrystalline diamond compact includes a substrate and a preformed polycrystalline diamond table bonded to the substrate. The table includes bonded diamond grains defining interstitial regions. The table includes an upper surface, a back surface bonded to the substrate, and at least one lateral surface extending therebetween. The table includes a first region extending inwardly from the upper surface and the lateral surface. The first region exhibits a first interstitial region concentration and includes at least one interstitial constituent disposed therein, which may be present in at least a residual amount and includes at least one metal carbonate and/or at least one metal oxide. The table includes a second bonding region adjacent to the substrate that extends inwardly from the back surface. The second bonding region exhibits a second interstitial region concentration that is greater than the first interstitial region concentration and includes a metallic infiltrant therein.
