Abstract

See full text

Embodiments of the invention relate to polycrystalline diamond (“PCD”) exhibiting enhanced diamond-to-diamond bonding. In an embodiment, PCD includes a plurality of diamond grains defining a plurality of interstitial regions. A metal-solvent catalyst occupies at least a portion of the plurality of interstitial regions. The plurality of diamond grains and the metal-solvent catalyst collectively exhibit a coercivity of about 115 Oersteads (“Oe”) or more and a specific magnetic saturation of about 15 Gauss·cm3/grams (“G·cm3/g”) or less. Other embodiments are directed to polycrystalline diamond compacts (“PDCs”) employing such PCD, methods of forming PCD and PDCs, and various applications for such PCD and PDCs in rotary drill bits, bearing apparatuses, and wire-drawing dies.
