    Abstract: 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.

    Abstract: Diamond bonded constructions include a diamond body comprising intercrystalline bonded diamond and interstitial regions. The body has a working surface and an interface surface, and may be joined to a metallic substrate. The body has a gradient diamond volume content greater about 1.5 percent, wherein the diamond content at the interface surface is less than 94 percent, and increases moving toward the working surface. The body may include a region that is substantially free of a catalyst material otherwise disposed within the body and present in a gradient amount. An additional material may be included within the body and be present in a changing amount. The body may be formed by high-pressure HPHT processing, e.g., from 6,200 MPa to 10,000 MPa, to produce a sintered body having a characteristic diamond volume fraction v. average grain size relationship distinguishable from that of diamond bonded constructions form by conventional-pressure HPHT processing.
