    摘要： Cutting elements for incorporation in a drill bit are provided having a body having an end face interfacing with an ultra hard material cutting layer. A main depression having a nonplanar surface is formed on the substrate and extending to the peripheral edge of the substrate subjected to the highest impact loads during drilling. This edge is immediately below the edge of the cutting layer which makes direct contact with the earth formations during drilling. The main depression is formed by forming a plurality of secondary depressions or steps. A second main depression is formed by forming a plurality of secondary depressions or steps. The second main depression also extends to the peripheral edge of the substrate. An ultra hard material layer is bonded to the end face of the cutting element body over the main depressions.

    摘要： Thermally stable diamond bonded materials and compacts include a diamond body having a thermally stable region and a PCD region, and a substrate integrally joined to the body. The thermally stable region has a microstructure comprising a plurality of diamond grains bonded together by a reaction with a reactant material. The PCD region extends from the thermally stable region and has a microstructure of bonded together diamond grains and a metal solvent catalyst disposed interstitially between the bonded diamond grains. The compact is formed by subjecting the diamond grains, reactant material, and metal solvent catalyst to a first temperature and pressure condition to form the thermally stable region, and then to a second higher temperature condition to both form the PCD region and bond the body to a desired substrate.

    摘要： Thermally stable ultra-hard polycrystalline materials and compacts comprise an ultra-hard polycrystalline body that wholly or partially comprises one or more thermally stable ultra-hard polycrystalline region. A substrate can be attached to the body. The thermally stable ultra-hard polycrystalline region can be positioned along all or a portion of an outside surface of the body, or can be positioned beneath a body surface. The thermally stable ultra-hard polycrystalline region can be provided in the form of a single element or in the form of a number of elements. The thermally stable ultra-hard polycrystalline region can be formed from precursor material, such as diamond and/or cubic boron nitride, with an alkali metal catalyst material. The mixture can be sintered by high pressure/high temperature process.

    摘要： PCD composite constructions comprise a diamond body bonded to a substrate. The diamond body comprises a thermally stable diamond bonded region that is made up of a single phase of diamond crystals bonded together. The diamond body includes a PCD region bonded to the thermally stable region and that comprises bonded together diamond crystals and interstitial regions interposed between the diamond crystals. The PCD composite is prepared by combining a first volume of PCD with a second volume of diamond crystal-containing material consisting essentially of a single phase of bonded together diamond crystals. A substrate is positioned adjacent to or joined to the first volume. The first and second volumes are subjected to high pressure/high temperature process conditions, during process the first and second volumes form a diamond bonded body that is attached to the substrate, and the second volume forms the thermally stable diamond bonded region.

    摘要： Cutting elements of this invention include an ultra hard body joined with a metallic substrate. The body includes an uppermost layer comprising a plurality of bonded ultra hard crystals and interstitial regions, and that defines a body working surface. The uppermost layer includes an outer region that is relatively more thermally stable than a remaining portion of the uppermost layer. The body further includes an intermediate layer joined to the uppermost layer, comprising a plurality of bonded ultra hard crystals, and having a wear resistance less than that of the uppermost layer remaining region. The body may additionally include a lowermost PCD layer that is interposed between and attached to the intermediate layer and the substrate.
