    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·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.

    摘要: Embodiments relate to methods of fabricating PCD materials by subjecting a mixture that exhibits a broad diamond particle size distribution to a HPHT process, PCD materials so-formed, and PDCs including a polycrystalline diamond table comprising such PCD materials. In an embodiment, a method includes subjecting a mixture to heat and pressure sufficient to form a PCD material. The mixture comprises a plurality of diamond particles exhibiting a diamond particle size distribution characterized, in part, by a parameter θ that is less than about 1.0, where θ = x 6 · σ , x is the average particle size of the diamond particle size distribution, and σ is the standard deviation of the diamond particle size distribution. In an embodiment, the diamond particle size distribution can be generally modeled by the following equation: C ⁢ ⁢ P ⁢ ⁢ F ⁢ ⁢ T 100 = D n - D S n D L n - D S n , wherein CPFT is the cumulative percent finer than, D is diamond grain size, DL is the largest-sized diamond grain, DS is the smallest-sized diamond grain, and n is a distribution modulus.
