    Abstract: Embodiments relate to polycrystalline diamond compacts and methods of manufacturing such compacts in which an at least partially leached polycrystalline diamond (“PCD”) table is infiltrated with first and second infiltrants. The first infiltrant includes a low viscosity cobalt-based and/or nickel-based alloy infiltrant. The second infiltrant (e.g., copper) is specifically selected to be more easily infiltrated and/or removed (e.g., leached) than a pure cobalt infiltrant. In an embodiment, a method includes forming a PCD table in the presence of a metal-solvent catalyst in a first high-pressure/high-temperature (“HPHT”) process. The PCD table may be at least partially leached to remove at least a portion of the metal-solvent catalyst therefrom. The leached PCD table and a substrate are subjected to a second HPHT process effective to bond the substrate to the leached PCD table while at least partially infiltrating the PCD table with at least the first and second infiltrants.

    Abstract: A method of processing a polycrystalline diamond element is disclosed. The method may include depositing a vaporized material over a selected portion of a polycrystalline diamond element to form a protective coating over the selected portion. The polycrystalline diamond element may include a polycrystalline diamond table. The method may also include exposing at least a portion of the polycrystalline diamond element to a leaching solution such that the leaching solution contacts an exposed surface region of the polycrystalline diamond table and at least a portion of the protective coating. The method may also include removing the polycrystalline diamond element from the leaching solution. The protective coating may be substantially impermeable to the leaching solution.

    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.
