    摘要: Graphite substrate holders for employment in apparatus for chemical vapor deposition of diamond decrease the tendency of the formed diamond sheets to crack or shatter upon separation from the substrates. Said holders and the substrates therein preferably have rounded edges, to suppress crack formation at sharp corners. The holders are preferably coated, at least in part, with a tie-layer and a hydride-forming metal such as niobium. Also, certain maximum distances between the edges of the holder and substrates are preferably maintained in order to prevent contact of diamond with a heated filament employed for thermal activation.

    摘要: The present invention provides a method for forming uniform CVD diamond coatings on a substrate wherein diamond is deposited on a plurality of substrates which are rotated in unison during the coating process to provide for more uniform radial growth. An advantageous substrate is a wire which can be coated with a layer of CVD diamond for making components in water-jet cutting apparatus, wire-drawing dies, or other tubular articles when the wire is separated from the resulting diamond tube. Identical tubes with higher uniformity in wall thickness are among the products which can be obtained. In addition, tubes having a uniform particle size distribution along their wall thickness which supports columnar diamond growth are also provided.

    摘要: A component comprised of a composite compact, preferably diamond, and a substrate bonded to the compact. A preferred embodiment of the component is a cutter for a drill bit. The compact is comprised of a layer of bonded diamond or boron nitride particles and a base layer of cemented carbide bonded, preferably under high temperatures and pressures, to the particulate layer. The particulate layer is degradable by expvsure to temperatures above a predetermined temperature. The substrate is bonded to the base layer of the compact with a filler metal which, to form a bond, requires the exposure of the surface to be bonded to a temperature substantially greater than the degradation temperature of the particulate layer. The component is fabricated by heating the base layer, filler metal and substrate to a temperature in excess of the degradation temperature while maintaining the temperature of the particulate layer below the degradation temperature via a heat sink.
