  • Polycrystalline diamond
    Patent number: 11969860
    Abstract: An embodiment of a PCD insert comprises an embodiment of a PCD element joined to a cemented carbide substrate at an interface. The PCD element has internal diamond surfaces defining interstices between them. The PCD element comprises a masked or passivated region and an unmasked or unpassivated region, the unmasked or unpassivated region defining a boundary with the substrate, the boundary being the interface. At least some of the internal diamond surfaces of the masked or passivated region contact a mask or passivation medium, and some or all of the interstices of the masked or passivated region and of the unmasked or unpassivated region are at least partially filled with an infiltrant material.
    Type: Grant
    Filed: September 16, 2022
    Date of Patent: April 30, 2024
    Assignees: Element Six Limited, Baker Hughes Incorporated
