    Abstract: Embodiments disclosed herein relate to superabrasive compacts, methods of making the same, and drill bits incorporating the same. For example, embodiments of a superabrasive compact disclosed herein (e.g., a PDC) may be formed by providing a superabrasive compact. The superabrasive compact includes a superabrasive body and a cemented carbide substrate bonded to the superabrasive body. The cemented carbide substrate includes a base surface, an interfacial surface bonded to the superabrasive body, and at least one peripheral surface extending between the base surface and the interfacial surface. After providing the superabrasive compact, the method includes lasing at least a portion of the peripheral surface of the cemented carbide substrate to form a corrosion-resistant layer

    Abstract: Some embodiments relate to cutting element assemblies including a superabrasive cutting element that may be axially compressed to enhance the damage tolerance thereof, enclosed in an enclosure that exposes the superabrasive cutting element therethrough, enclosed in an enclosure that restricts rotation of the superabrasive cutting element, or combinations of the foregoing. Additionally, some embodiments relate to cutting element assemblies in which a superabrasive cutting element is mechanically fastened to a base, such as a substrate or directly to a bit body of a rotary drill bit. Some embodiments also relate to cutting element assemblies including one or more superabrasive cutting elements that are rotatable about a longitudinal axis of the cutting element assembly, that may be axially compressed to enhance the damage tolerance thereof, that may be enclosed in an enclosure that exposes the superabrasive cutting element therethrough, or combinations thereof.

    Abstract: Embodiments of the invention relate to polycrystalline diamond compacts (“PDC”) exhibiting enhanced diamond-to-diamond bonding. In an embodiment, a PDC includes a polycrystalline diamond (“PCD”) table bonded to a substrate. At least a portion of the PCD table includes a plurality of diamond grains defining a plurality of interstitial regions. The plurality of interstitial regions includes a metal-solvent catalyst. The plurality of diamond grains exhibit an average grain size of about 30 μm or less. The plurality of diamond grains and the metal-solvent catalyst collectively exhibit an average electrical conductivity of less than about 1200 S/m. Other embodiments are directed to PCD, employing such PCD, methods of forming PCD and PDCs, and various applications for such PCD and PDCs in rotary drill bits, bearing apparatuses, and wire-drawing dies.
