  • Polycrystalline diamond structure
    Patent number: 8590643
    Abstract: A PCD structure comprising a first region, in a state of residual compressive stress, and a second region in a state of residual tensile stress adjacent the first region; the first and second regions each formed of respective PCD grades and directly bonded to each other by intergrowth of diamond grains, the PCD grades having transverse rupture strength (TRS) of at least 1,200 MPa. A third region in a state of residual compressive stress may also be provided such that the second region is disposed between the first and third regions and is bonded to the first and third regions by intergrowth of diamond grains.
