    摘要: In various embodiments, a polycrystalline diamond compact (“PDC”) comprises a substrate including an interfacial surface having a raised region. The PDC comprises a polycrystalline diamond (“PCD”) table bonded to the interfacial surface of the substrate. The PCD table defines an upper surface and exhibits a thickness over the raised region. The PCD table includes a plurality of bonded diamond grains defining a plurality of interstitial regions. A first region of the PCD table adjacent to the substrate includes metal-solvent catalyst disposed interstitially between the bonded diamond grains thereof, and a leached second region of the PCD table extends inwardly from the upper surface. The interstitial regions of the leached second region are depleted of metal-solvent catalyst. The geometry of the PCD table and raised region may be selected so that residual compressive stresses therein are retained to a sufficient level after leaching to provide a damage tolerant/thermally-stable PCD table.

    摘要: In various embodiments, a polycrystalline diamond compact (“PDC”) comprises a substrate including an interfacial surface having a raised region. In an embodiment, a PDC comprises a substrate including an interfacial surface having a generally cylindrical raised region and a peripheral region extending about the generally cylindrical raised region. The generally cylindrical raised region extends to a height above the peripheral region of about 450 μm or less. The PDC includes a PCD table bonded to the interfacial surface of the substrate. The PCD table includes an upper surface and at least one peripheral surface, and includes a plurality of bonded diamond grains defining interstitial regions. At least a portion of the interstitial regions includes a metallic constituent therein. In another embodiment, instead of employing a generally cylindrical raised region, the interfacial surface may include a plurality of raised arms extending above the face. Each raised arm extends radially and circumferentially.

    摘要: In an embodiment, a polycrystalline diamond compact (“PDC”) includes a substrate and a pre-sintered polycrystalline diamond (“PCD”) table bonded to the substrate. The pre-sintered PCD table includes an upper surface, a back surface bonded to the substrate, and at least one lateral surface extending between the upper surface and the back surface. The pre-sintered PCD table includes a region including at least a residual amount of at least one interstitial constituent disposed in at least a portion of the interstitial regions thereof, and a bonding region. The at least one interstitial constituent includes at least one metal carbonate and/or at least one metal oxide. The region extends inwardly from the upper surface and the at least one lateral surface.
