摘要： A cutting element is provided, including a substrate and an ultra-hard material layer formed over the substrate. At one end of the substrate is an interface surface that interfaces with the ultra- hard material layer to bond the layer to the substrate. The interface surface includes a first or outer annular section that extends to the peripheral edge of the substrate, and a second or inner section that is radially inside the first section. The interface surface includes several spaced-apart projections arranged in an annular row. In one aspect, each projection has an upper surface that defines a groove bisecting the projection. In another aspect, the interface surface may include a bridge coupling adjacent projections.

摘要： Thermally stable polycrystalline constructions comprise a diamond body joined with a substrate, and may have a nonplanar interface. The construction may include an interlayer interposed between the diamond body and substrate. The diamond body preferably has a thickness greater than about 1.5 mm, and comprises a matrix phase of bonded together diamond crystals and interstitial regions disposed therebetween that are substantially free of a catalyst material used to sinter the diamond body. A replacement material is disposed within the interstitial regions. A population of the interstitial regions may include non-solvent catalyst material and/or an infϊltrant aid disposed therein. The diamond body comprises two regions; namely, a first region comprising diamond grains that may be sized smaller than diamond grains in a second region, and/or the first region may comprise a diamond volume that is greater than that in the second region.

摘要： In one aspect, a vacuum-sealed can is used during the bonding process to improve the properties of an infiltrated TSP cutting element. In one embodiment, ultra hard diamond crystals and a catalyst material are sintered to form a polycrystalline diamond material (PCD). This PCD material is leached to remove the catalyst, forming a thermally stable product (TSP). The TSP material and a substrate are placed into an enclosure such as a can assembly, heated, and subjected to a vacuum in order to remove gas, moisture and other residuals that can inhibit infiltration of the infiltrant into the TSP layer. The can assembly is then subjected to high temperature, high pressure bonding to bond the TSP material to the substrate. During bonding, material from the substrate infiltrates the TSP layer. In another aspect, an insulator material may be used during a bonding process.

摘要： A polycrystalline diamond layer (27) is bonded to a cemented metal carbide substrate (21) by this process. A layer of dense high shear compaction material (27) including diamond or cubic boron nitride particles is placed adjacent to a metal carbide substrate (21). The particles of diamond have become rounded instead of angular due to high shear compaction in a multiple roller process. The volatiles in the high shear compaction material are removed and binder decomposed at high temperature, for example, 950 DEG C, leaving residual amorphous carbon or graphite in a layer of ultra hard material particles on the carbide substrate. The substrate and layer assembly is then subjected to a high pressure, high temperature process, thereby sintering the ultra hard particles to each other to form a polycrystalline ultra hard layer (27) bonded to the metal carbide substrate (21). The layer of high shear compaction material is also characterized by a particle size distribution including larger and smaller particles that are distributed uniformly throughout the layer.
