    摘要: In an embodiment, a polycrystalline diamond compact (“PDC”) includes a substrate and a polycrystalline diamond (“PCD”) table bonded to the substrate. The PCD table includes a first PCD region having bonded-together diamond grains, with the first PCD region exhibiting a first thermal stability and a first diamond density. The PCD table further includes an intermediate second PCD region bonded to the substrate and disposed between the first PCD region and the substrate. The intermediate second PCD region includes bonded-together diamond grains. The intermediate second PCD region exhibits a second thermal stability that is less than that of the first thermal stability of the first PCD region and a second diamond density less than that of the first diamond density of the first PCD region.

    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.
