摘要： The present disclosure relates to cutting elements incorporating polycrystalline diamond bodies used for subterranean drilling applications, and more particularly, to polycrystalline diamond bodies having a high diamond content which are configured to provide improved properties of thermal stability and wear resistance, while maintaining a desired degree of impact resistance, when compared to prior polycrystalline diamond bodies. In various embodiments disclosed herein, a cutting element with high diamond content includes a modified PCD structure and/or a modified interface (between the PCD body and a substrate), to provide superior performance.

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 diamond bonded construction comprise a diamond bonded body including a thermally stable region, comprising a plurality of diamond grains bonded together by a reaction product of the diamond grains with a reactant such as Si, and a polycrystalline diamond region, comprising intercrystalline bonded diamond and a catalyst material. The body further comprises a ceramic compound formed by reaction of an Nb, Zr, Ti, or Mo getter material with a gaseous element generated during HPHT sintering of the diamond bonded body. The diamond bonded body may comprise from 0.1 to 15 percent by weight of the ceramic compound. The diamond bonded body can be formed during a single HPHT process operated at different temperatures when the reactant has a melting temperature above the catalyst material. The construction may include a metallic substrate attached to the diamond bonded body to facilitate use as a wear or cutting element.

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.
