Publication number: 20140197227Abstract: A method for the joining of ceramic pieces with a hermetically sealed joint comprising brazing a continuous layer of joining material between the two pieces. The wetting and flow of the joining material is controlled by the selection of the joining material, the joining temperature, the time at temperature, the joining atmosphere, and other factors. The ceramic pieces may be aluminum nitride and the pieces may be brazed with an aluminum alloy under controlled atmosphere. The joint material is adapted to later withstand both the environments within a process chamber during substrate processing, and the oxygenated atmosphere which may be seen within the shaft of a heater or electrostatic chuck.Type: ApplicationFiled: November 20, 2012Publication date: July 17, 2014Applicant: Component Re-Engineering Company, Inc.Inventors: Alfred Grant Elliot, Brent Donald Alfred Elliot, Frank Balma, Richard Erich Schuster, Dennis George Rex, Alexander Veytser

Patent number: 8763883Abstract: A method for assembling at least two parts made of silicon carbide-based materials by non-reactive brazing is disclosed. The two parts are contacted with a non-reactive brazing composition. The assembly formed by the parts and the brazing composition is heated to a brazing temperature sufficient to melt the brazing composition. The parts and the brazing composition are cooled so that, after solidification of the brazing composition, a moderately refractory joint is formed. The non-reactive brazing composition is a binary alloy composed, in mass percentages, of about 46% to 99% silicon and 54% to 1% neodymium.Type: GrantFiled: September 3, 2010Date of Patent: July 1, 2014Assignee: Commissariat à l'énergie atomique et aux énergies alternativesInventors: Valérie Chaumat, Jean-François Henne

Patent number: 8752753Abstract: A method of construction of a tungsten carbide/TSP insert for hard facing a wear surface comprises the steps of forming a tungsten carbide body (12) in a mold. After the molding step, a channel section slot (24) or pocket (24?) is created in the body before it has hardened substantially. The body is then heat-treated to harden it. A TSP body (32) is fitted in the slot/pocket (24/24?) so that it is a close sliding fit between the sides (18) of the slot, and is of the same depth as the slot. The TSP is (preferably) brazed into the slot. The insert has pips (30) on its edges (18) to facilitate welding to a substrate prior to a final brazing step.Type: GrantFiled: December 22, 2009Date of Patent: June 17, 2014Inventor: Mark Russell

Patent number: 8740048Abstract: Thermally stable polycrystalline constructions comprise a body having a polycrystalline ultra-hard phase and a plurality of empty voids. A population of the voids can be filled with a reaction product. The body is substantially free of a catalyst material. The construction comprises a first support member attached to the body by a first braze material. A second support member is attached to the body and the first support member by a second braze material. The construction may include a third support member attached to the body that is integral or separate from one of the other support members. The braze materials used to attached the support members can be the same or different, as can be the materials used to form the different support members.Type: GrantFiled: June 29, 2010Date of Patent: June 3, 2014Assignee: Smith International, Inc.Inventors: Georgiy Voronin, J.
