In an embodiment, the plurality of PCD bearing elements of one or more of the bearing assemblies disclosed herein include at least one first PCD bearing element. At least a portion of the first PCD bearing element exhibits a coercivity of about 125 Oersteds or more and a specific magnetic saturation of about 14 Gauss·cm3/gram or less. The first PCD bearing element includes a bearing surface with at least one groove formed therein. In an embodiment, the plurality of PCD bearing elements also include at least one second PCD bearing element. The second PCD bearing element exhibits a coercivity that is less than and a specific magnetic saturation that is greater than the first PCD bearing element.

摘要： Embodiments relate to polycrystalline diamond compacts ("PDCs") and methods of manufacturing such PDCs in which an at least partially leached polycrystalline diamond ("PCD") table is infiltrated with a low viscosity cobalt-based alloy 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 method includes at least partially leaching the PCD table to remove at least a portion of the metal-solvent catalyst therefrom to form an at least partially leached PCD table. The method includes subjecting the at least partially leached PCD table and a substrate to a second HPHT process effective to at least partially infiltrate the at least partially leached PCD table with an alloy infiltrant comprising at least one of a cobalt- based or nickel based alloy infiltrant having a composition at or near a eutectic composition of the alloy infiltrant.
