    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： A heating apparatus for induction heating is disclosed. The heating apparatus may comprise a bearing ring, at least one bearing element disposed in the bearing ring, and a braze material adjacent to the at least one bearing element and the bearing ring. The heating apparatus may additionally comprise an inductor positioned radially adjacent to at least a portion of the bearing ring. A current source may be electrically coupled to the inductor. A bearing orienting member may also abut a surface of the at least one bearing element. The bearing orienting member may orient a surface of the at least one bearing element. A heating method is also disclosed.
