摘要： Embodiments of the invention relate to polycrystalline diamond ("PCD") exhibiting enhanced diamond-to-diamond bonding. In an embodiment, polycrystalline diamond compact ("PDC") includes a PCD table having a maximum thickness. At least a portion of the PCD table 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 Oersteds ("Oe") or more and a specific magnetic saturation of about 15 Gauss·cm 3 /grams ("G·cm 3 /g") or less. The PDC includes a substrate having an interfacial surface that is bonded to the PCD table. The interfacial surface exhibits a substantially planar topography. Other embodiments are directed to methods of forming PCD and PDCs, and various applications for such PCD and PDCs in rotary drill bits, bearing apparatuses, and wire-drawing dies.

摘要： Superabrasive elements, methods of fabricating such elements, and applications utilizing such elements. In one embodiment, a superabrasive element includes a mass of polycrystalline diamond including ultra-dispersed diamond grain structures present in an amount greater than zero weight percent and less than about 75 weight percent of the mass of polycrystalline diamond. Various structures and apparatuses that utilize the superabrasive elements, such as polycrystalline diamond compacts (PDCs) and drill bits are disclosed. Methods of manufacture are also disclosed.
