POLYCRYSTALLINE DIAMOND COMPACTS, METHOD OF FABRICATING SAME, AND VARIOUS APPLICATIONS |
摘要 |
<p>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 -cm3/grams ("G-cm3/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.</p> |
