    摘要: Thermally stable diamond constructions comprise a diamond body having a plurality of bonded diamond crystals, a plurality of interstitial regions disposed among the crystals, and a substrate attached to the body. The body includes a working surface and a side surface extending away from the working surface to the substrate. The body comprises a first region adjacent the side surface that is substantially free of a catalyst material and that extends a partial depth into the diamond body. The first region can further extend to at least a portion of the working surface and a partial depth therefrom into the diamond body. The diamond body can be formed from natural diamond grains and/or a mixture of natural and synthetic diamond grains. A surface of the diamond body is treated to provide the first region, and before treatment is finished to an approximate final dimension.

    摘要: Thermally stable diamond constructions comprise a diamond body having a plurality of bonded diamond crystals and a plurality of interstitial regions disposed among the crystals. A metallic substrate is attached to the diamond body. A working surface is positioned along an outside portion of the diamond body, and the diamond body comprises a first region that is substantially free of a catalyst material, and a second region that includes the catalyst material. The diamond body first region extends from the working surface to depth of at least about 0.02 mm to a depth of less than about 0.09 mm. The diamond body includes diamond crystals having an average diamond grain size of greater than about 0.02 mm, and comprises at least 85 percent by volume diamond based on the total volume of the diamond body.

    摘要: Polycrystalline diamond (PCD) carbide composites of this invention have a microstructure comprising a plurality of granules formed from PCD, polycrystalline cubic boron nitride, or mixture thereof, that are distributed within a substantially continuous second matrix region that substantially surrounds the granules and that is formed from a cermet material. In an example embodiment, the granules are polycrystalline diamond and the cermet material is cemented tungsten carbide. PCD carbide composites of this invention display improved properties of fracture toughness and chipping resistance, without substantially compromising wear resistance, when compared to conventional pure PCD materials.

    摘要: Ultrahard composite constructions comprise a plurality of first phases dispersed within a matrix second phase, wherein each can comprise an ultrahard material including PCD, PcBN, and mixtures thereof. The constructions are formed from a plurality of granules that are combined and sintered at HP/HT conditions. The granules include a core surrounded by a shell and both are formed from an ultrahard material or precursor comprising an ultrahard constituent for forming the ultrahard material. When sintered, the cores form the plurality of first phases, and the shells form at least a portion of the second phase. The ultrahard material used to form the granule core may have an amount of ultrahard constituent different from that used to form the granule shell to provide desired different properties. The ultrahard constituent in the granule core and shell can have approximately the same particle size.
