    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.

    摘要: Embodiments of the invention relate to polycrystalline diamond compacts (“PDC”) exhibiting enhanced diamond-to-diamond bonding. In an embodiment, PDC includes a sintered substantially single-phase polycrystalline diamond (“PCD”) body consisting essentially of bonded-together diamond grains exhibiting a morphology different than that of a PCD body formed by sintering diamond crystals. A substrate is bonded to the sintered substantially single-phase PCD body. Other embodiments are directed to methods of forming such PDCs, and various applications for such PDCs in rotary drill bits, bearing apparatuses, and wire-drawing dies.
