  • Polycrystalline tables having polycrystalline microstructures and cutting elements including polycrystalline tables
    Patent number: 8475918
    Abstract: Cutting elements comprise a substrate and an unleached polycrystalline table attached on an end of the substrate. The polycrystalline table comprises a plurality of continuously inter-bonded grains of a superhard material and a quantity of catalyst material disposed in interstitial spaces between grains of the plurality of continuously inter-bonded grains of a superhard material. A mean grain size of the plurality of continuously inter-bonded grains is at least substantially uniform throughout the polycrystalline table and the quantity of catalyst material varies across the polycrystalline table in a direction parallel to a central axis of the polycrystalline table.
    Type: Grant
    Filed: October 29, 2010
    Date of Patent: July 2, 2013
    Assignees: Baker Hughes Incorporated, Element Six Limited
    Inventors: Anthony A. DiGiovanni, Michael L. Fish

  • Synthesis of ultra-hard abrasive particles
    Patent number: 5385715
    Abstract: Friable abrasive particles, particularly diamond particles, are produced by causing suitable material, such as a chloride salt, to be occluded in the particles during their manufacture and then removing some of this material, for example, by leaching.
