  • Polycrystalline diamond compact with increased impact resistance
    Patent number: 9764387
    Abstract: A polycrystalline diamond (PCD) with diamond grains includes a first zone of the diamond grains and a second zone of the diamond grains. The first zone forms a working surface and a first catalyzing material is disposed within voids of the diamond grains in the first zone. A second catalyzing material is bonded to the diamond grains disposed in the second zone. The first catalyzing material in the first zone is connected to the diamond grains disposed in the first zone less intimately than the second catalyzing material is bonded to the diamond grains in the second zone.
    Type: Grant
    Filed: February 17, 2015
    Date of Patent: September 19, 2017
