Abstract:
Embodiments of the invention relate to polycrystalline diamond compacts (“PDC”) exhibiting enhanced diamond-to-diamond bonding. In an embodiment, PDC includes a sintered substantially single-phase polycrystalline diamond (“PCD”) body consisting essentially of bonded-together diamond grains exhibiting a morphology different than that of a PCD body formed by sintering diamond crystals. A substrate is bonded to the sintered substantially single-phase PCD body. Other embodiments are directed to methods of forming such PDCs, and various applications for such PDCs in rotary drill bits, bearing apparatuses, and wire-drawing dies.
