    Abstract: Embodiments relate to polycrystalline diamond compacts (“PDCs”) including a polycrystalline diamond (“PCD”) table having a diamond grain size distribution selected for improving leachability. In an embodiment, a PDC includes a PCD table bonded to a substrate. The PCD table includes diamond grains exhibiting diamond-to-diamond bonding therebetween. The diamond grains includes a first amount being about 30 to about 65 volume % of the diamond grains and a second amount being about 18 to about 65 volume % of the diamond grains. The first amount exhibits a first average grain size of about 8 μm to about 22 μm. The second amount exhibits a second average grain size that is greater than the first average grain size and is about 15 μm to about 50 μm. Other embodiments are directed methods of forming PDCs, and various applications for such PDCs in rotary drill bits, bearing apparatuses, and wire-drawing dies.

    Abstract: Embodiments relate to polycrystalline diamond compacts (“PDCs”) including a polycrystalline diamond (“PCD”) table having a diamond grain size distribution selected for improving performance and/or leachability. In an embodiment, a PDC includes a PCD table bonded to a substrate. The PCD table includes a plurality of diamond grains exhibiting diamond-to-diamond bonding therebetween. The plurality of diamond grains includes a first amount being about 5 weight % to about 65 weight % of the plurality of diamond grains and a second amount being about 18 weight % to about 95 weight % of the plurality of diamond grains. The first amount exhibits a first average grain size of about 0.5 μm to about 30 μm. The second amount exhibits a second average grain size that is greater than the first average grain size and is about 10 μm to about 65 μm. Other embodiments are directed to methods of forming PDCs, and various applications for such PDCs in rotary drill bits, bearing apparatuses, and wire-drawing dies.

    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.
