Polycrystalline diamond compacts, methods of fabricating same, and applications using same










Image Number 3 for United States Patent #7842111.

Embodiments of the present invention relate to PDCs including a PCD table having an exterior cutting region that exhibits enhanced thermal stability. In one embodiment, a method comprises forming an assembly including a first region having non-diamond carbon material and a second region having a plurality of diamond particles. The method comprises subjecting the assembly to heat and pressure sufficient to form the PDC. In another embodiment, a PDC comprises a substrate and a PCD table bonded to the substrate. The PCD table comprises an exterior cutting region including a plurality of elongated diamond grains that are generally randomly oriented. The PCD table comprises a main region positioned between the substrate and exterior cutting region, and including a plurality of bonded diamond grains. In another embodiment, the first region may include coarse-sized diamond particles instead of non-diamond carbon material.
