  • LEACHED DIAMOND ELEMENTS AND LEACHING SYSTEMS, METHODS AND ASSEMBLIES FOR PROCESSING DIAMOND ELEMENTS
    Publication number: 20230250026
    Abstract: Method of processing a polycrystalline diamond element may include laser ablating at least a portion of a polycrystalline diamond element to form a laser-shaped surface and exposing at least a portion of the laser-shaped surface to a leaching solution to define a leached polycrystalline diamond volume and an unleached polycrystalline diamond volume.
    Type: Application

  • Leached superabrasive elements and leaching systems, methods and assemblies for processing superabrasive elements
    Patent number: 11618718
    Abstract: A polycrystalline diamond element includes a polycrystalline diamond table having a body of bonded diamond particles with interstitial regions. A first volume of the body includes an interstitial material and a second volume of the body has a lower concentration of interstitial material within the interstitial regions than the first volume. The polycrystalline diamond element includes an element face and a peripheral surface. The first volume is adjacent to a central portion of the element face and the second volume is adjacent to the peripheral surface. A method of processing a polycrystalline diamond element includes forming a concave region in the polycrystalline diamond element, exposing at least a portion of the concave region to a leaching solution, and removing at least a portion of the polycrystalline diamond element that was exposed to the leaching solution from the polycrystalline diamond element.
