  • Publication number: 20200256379
    Abstract: Embodiments of the invention relate to bearing apparatuses in which one bearing surface of the bearing apparatus includes diamond, while another bearing surface includes a non-diamond superhard material (e.g., silicon carbide). For example, a bearing apparatus may include a bearing stator assembly and a bearing rotor assembly. The bearing stator assembly and bearing rotor assembly each include a support ring and one or more superhard bearing elements generally opposed to one another. The bearing surface(s) of the rotor or stator may include diamond, while the bearing surface(s) of the other of the rotor or stator do not include diamond. Another bearing apparatus may include both thrust- and radial bearing components. The generally opposed thrust-bearing elements may include diamond, while the generally opposed radial bearing elements may not include diamond, but include a non-diamond superhard material, such as silicon carbide.

  • Publication number: 20190242193
    Abstract: In an embodiment, a polycrystalline diamond compact includes a substrate, and a polycrystalline diamond (“PCD”) table bonded to the substrate and including an exterior working surface, at least one lateral surface, and a chamfer extending between the exterior working surface and the at least one lateral surface. The PCD table includes bonded diamond grains defining interstitial regions. The PCD table includes a first region adjacent to the substrate and a second leached region adjacent to the first region and extending inwardly from the exterior working surface to a selected depth. At least a portion of the interstitial regions of the first region include an infiltrant disposed therein. The interstitial regions of the second leached region are substantially free of metal-solvent catalyst. The second region is defined by the exterior working surface, the lateral surface, the chamfer, and a generally horizontal boundary located below the chamfer.

  • Patent number: 10309158
    Abstract: In an embodiment, a method of fabricating a polycrystalline diamond compact (“PDC”) includes forming a polycrystalline diamond (“PCD”) table in the presence of a metal-solvent catalyst in a first high-pressure/high-temperature (“HPHT”) process. The PCD table includes bonded diamond grains defining interstitial regions, with the metal-solvent catalyst disposed therein. The method includes at least partially leaching the PCD table to remove at least a portion of the metal-solvent catalyst therefrom. The method includes subjecting the at least partially leached PCD table and a substrate to a second HPHT process under diamond-stable temperature-pressure conditions to partially infiltrate the at least partially leached PCD table with an infiltrant. A maximum temperature (T), a total process time (t), and a maximum pressure (P) of the second HPHT process are chosen so that ? is about 2° Celsius·hours/gigapascals (“° C.·h/GPa”) to about 325° C.·h/GPa, with ? represented as ?=T·t/P.

  • Patent number: 10179390
    Abstract: 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 a cobalt-based alloy infiltrant having a composition at or near a eutectic composition of the cobalt-based alloy infiltrant.
