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.

摘要： Ultrahard composite constructions comprise a plurality of first phases dispersed within a matrix second phase, wherein each can comprise an ultrahard material including PCD, PcBN, and mixtures thereof. The constructions are formed from a plurality of granules that are combined and sintered at HP/HT conditions. The granules include a core surrounded by a shell and both are formed from an ultrahard material or precursor comprising an ultrahard constituent for forming the ultrahard material. When sintered, the cores form the plurality of first phases, and the shells form at least a portion of the second phase. The ultrahard material used to form the granule core may have an amount of ultrahard constituent different from that used to form the granule shell to provide desired different properties. The ultrahard constituent in the granule core and shell can have approximately the same particle size.

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： A method for manufacturing an ultrahard compact includes assembling a mass of ultrahard material with a mass of substrate material such that the mass of ultrahard material extends radially outward a greater extent than the substrate material to compensate for a difference in the radial shrinkage of the ultrahard material compared to the substrate material during a sintering process. The method may further includes subjecting the assembled compact to a high pressure high temperature process mat results in the forming of an ultrahard compact including an ultrahard layer integrally bonded with a substrate.

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.
