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.
