    Abstract: Diamond bonded constructions comprise a polycrystalline diamond body having a matrix phase of bonded-together diamond grains and a plurality of interstitial regions between the diamond grains including a catalyst material used to form the diamond body disposed within the interstitial regions. A sintered thermally stable diamond element is disposed within and bonded to the diamond body, and is configured and positioned to form part of a working surface. The thermally stable diamond element is bonded to the polycrystalline diamond body, and a substrate is bonded to the polycrystalline diamond body. The thermally stable diamond element comprises a plurality of bonded-together diamond grains and interstitial regions, wherein the interstitial regions are substantially free of a catalyst material used to make or sinter the thermally stable diamond element. A barrier material may be disposed over or infiltrated into one or more surfaces of the thermally stable diamond 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.

    Abstract: PCD constructions as disclosed comprise a ultra-hard body attached with a metallic substrate along a substrate extending between the body and the substrate. The construction includes a protective feature or element that is configured to protect a metal rich region or zone existing in the construction from unwanted effects of corrosion or erosion. The protective element extends from the body over the interface and along a portion of the substrate and may be integral with the.

    Abstract: Roller cutters comprise a diamond-bonded body joined to an infiltration substrate. An extension is joined to the substrate and includes first section having a diameter sized the same as the substrate, and an integral second section having a diameter smaller than the substrate. The extension is joined to the substrate during an HPHT process. The first section has a thickness greater than that of the infiltration substrate. The second section has an axial length greater than the combined thickness of the substrate and the first section. The extension has a strength and/or toughness greater than the substrate as a result of its material composition, e.g., the amount of binder phase material and/or the size of hard phase material. The roller cutter is rotatably disposed within a pocket internal cavity, wherein the pocket is attached to a drill bit.
