Patent number: 10920303Abstract: Induced material segregation methods of manufacturing a polycrystalline diamond compact (PDC) cutter result in formation of a polycrystalline diamond/tungsten carbide (WC) composite material having a smooth compositional gradient from maximum WC concentration at one face to maximum diamond concentration at another face. Because the compositional gradient is smooth, very little or no mismatch of coefficient of thermal expansion occurs, which improves a service lifetime of the PDC cutter.Type: GrantFiled: May 28, 2015Date of Patent: February 16, 2021Assignee: Halliburton Energy Services, Inc.Inventors: Zachary Ryan Murphree, Andy Cheng Chang, Gagan Saini

Patent number: 10655398Abstract: A cutter for a drill bit and method of manufacturing same is disclosed. The cutter has a non-leached polycrystalline diamond (PCD) table bonded to a substrate and a leached PCD table bonded to one or both of the substrate and non-leached PCD table. The leached PCD table may be ring-shaped and acts as the working surface of the cutting element. It may have a jagged inner surface which cooperates with complementary jagged-shaped outer surface of the non-leached PCD table to prevent rotation of the leached PCD table relative to the non-leached PCD table during a cutting operation. A surface of the leached PCD table may be tapered and fit together in a complementary manner with an oppositely tapered surface of the non-leached PCD table so as to mechanically lock the leached PCD table to the non-leached PCD table.Type: GrantFiled: June 26, 2015Date of Patent: May 19, 2020Assignee: Halliburton Energy Services, Inc.Inventor: Gagan Saini

Publication number: 20180214952Abstract: A fiber-reinforced cutting element for a drill bit and method of manufacturing same is disclosed. A plurality of fibers are formed in and embedded between the PCD table and the attached substrate. The fibers enhance the thermo-mechanical integrity of the cutting element as well as its wear and abrasion resistance and also help to minimize the failure of the bond between the PCD table and the substrate. The fibers may be coated with a ceramic material to help withstand the high temperatures during the HTHP sintering process used to form the PCD table. The PCD table is leached following the HTHP press cycle thereby partially exposing the fibers. The PCD table with partially exposed fibers is then bonded to a substrate through an infiltration, hot pressing or sintering process. A binder may optionally be used to enhance the binding of the substrate to the PCD table.Type: ApplicationFiled: September 8, 2015Publication date: August 2, 2018Inventor: Gagan Saini

Publication number: 20180202234Abstract: A PCD cutter formed by a reactive/exothermic bond formed between the diamond table and the substrate. The bond is formed by applying a small pulse of localized energy to a bonding agent containing exothermic reactive materials which is disposed at the interface of the diamond table and the substrate. The bonding agent may be formed by depositing a plurality of alternating layers of exothermic foils at the interface between the polycrystalline diamond table and the substrate. Additional layers may also be deposited between the polycrystalline diamond table and the plurality of layers of exothermic foils and between the foils and the substrate. One or more refractory layers may also be disposed between the layers of exothermic material and a masking or non-wetting material may be applied to one or more sides of the substrate and diamond table.Type: ApplicationFiled: August 17, 2015Publication date: July 19, 2018Inventors: Gagan Saini, Grant O.
