Patent number: 10046436Abstract: A polycrystalline diamond compact (PDC) is fabricated using a process of delayed diffusion (i.e., post-sintering) of a diffusion species (i.e., a metalloid) introduced from the back side of a carbide further away from the diamond grit or from the flank side of the carbide, as opposed to the side of the carbide adjacent to the diamond grit. The process of fabricating the PDC includes depositing, in a metal container, a synthetic diamond grit, a carbide, and a diffusion species, then applying a high pressure and high temperature (HPHT) to the contents of the metal container wherein (1) the carbide diffuses across the diamond grit, and (2) the diffusion species diffuses across the carbide followed by the diamond grit, thus providing a protective coating to the PDC.Type: GrantFiled: August 17, 2015Date of Patent: August 14, 2018Assignee: Diamond Innovations, Inc.Inventors: Gary Martin Flood, Joel Vaughn

An angle encoder is disposed on the end of the shaft distal to the gear box. The gear box's output shaft, the torque sensor's cylindrical shaft hubs and associated couplings are arranged such that they are directly aligned with the shaft. The test system has been designed to take automated torque and angle readings from a shaft capable of rotary motion.Type: GrantFiled: August 14, 2006Date of Patent: March 23, 2010Assignee: Steorn LimitedInventors: Shaun David McCarthy, Michael Andrew Daly, Alan Simpson, Ciaran Mythen, Martin Flood, Guillaume Reux, David King

Patent number: 6045440Abstract: The present invention relates to supported polycrystalline diamond compact cutters (PDC cutters) made under high temperature, high pressure (HT/HP) processing conditions, and more particularly to supported PDC cutters having non-planar cutting surfaces. More specifically, the present invention is for an oriented PDC cutter wherein chips and debris are funneled away from the cutting edge by a raised top surface of the polycrystalline diamond layer (PCD layer). The redirection of the debris is achieved by the creation of high and low regions on the PCD layer, of which there can be a variety of different surface geometry's. Thus, an object of the present invention is to provide a PDC cutter with improved performance through channeling debris away from its cutting edge.Type: GrantFiled: November 20, 1997Date of Patent: April 4, 2000Assignee: General Electric CompanyInventors: David Mark Johnson, Gary Martin Flood, Henry Samuel Marek

Patent number: 5848657Abstract: The present invention relates to a novel domed polycrystalline diamond cutting element wherein a hemispherical diamond layer is bonded to a tungsten carbide substrate, commonly referred to as a tungsten carbide stud. Broadly, the inventive cutting element includes a metal carbide stud having a proximal end adapted to be placed into a drill bit and a distal end portion. A layer of cutting polycrystalline abrasive material disposed over said distal end portion such that an annulus of metal carbide adjacent and above said drill bit is not covered by said abrasive material layer. The geometry of the diamond cutting element provides control of interfacial stresses and reduces fabrication costs. The diamond cutting element may contain a pattern of ridges or bumps integrally formed in the abrasive layer which ridges are designed to cause high localized stresses in the rock, thus starting a crack. By initiating cracks in localized areas, the crushing action could be performed with less force.Type: GrantFiled: December 27, 1996Date of Patent: December 15, 1998Assignee: General Electric CompanyInventors: Gary Martin Flood, David Mark Johnson, Friedel Siegfried Knemeyer, Bradley Earl Williams
