Patent number: 10934605Abstract: Methods are provided for synthesizing high purity niobium or rhenium powders by a combustion reaction. The methods can include: forming a combustion synthesis solution by dissolving in water an oxidizer, a fuel, and at least one base-soluble, ammonium salt of niobium or rhenium in amounts that yield a stoichiometric burn when combusted; and heating the combustion synthesis solution to a temperature sufficient to substantially remove the water and to initiate a self-sustaining combustion reaction.Type: GrantFiled: October 17, 2017Date of Patent: March 2, 2021Assignee: Battelle Memorial InstituteInventors: John G. Frye, Kenneth Scott Weil, Curt A. Lavender, Jin Yong Kim

Patent number: 10378094Abstract: Reactive coating processes are provided that can include providing a coating material, reacting the coating material to form a shell about the coating material, contacting the shelled coating material with a substrate to be coated, depositing the coating material from within the shelled coating material on the substrate, and removing the shells from the substrate. Coating materials may be deposited upon a substrate to be coated and reacted to form a shell about the coating material. The coating materials can be particles and a shell can be formed about each of the individual particles.Type: GrantFiled: July 1, 2016Date of Patent: August 13, 2019Assignee: Battelle Memorial InstituteInventors: Jung-Pyung Choi, Jeffrey W.

Publication number: 20180037975Abstract: Nanocrystalline metal powders comprising tungsten, molybdenum, rhenium or niobium can be synthesized using a combustion reaction. Methods for synthesizing the nanocrystalline metal powders are characterized by forming a combustion synthesis solution by dissolving in water an oxidizer, a fuel, and a base-soluble, ammonium precursor of tungsten, molybdenum, rhenium, or niobium in amounts that yield a soichiometric burn when combusted. The combustion synthesis solution is then heated to a temperature sufficient to substantially remove water and to initiate a self-sustaining combustion reaction. The resulting powder can be subsequently reduced to metal form by heating in a reducing gas environment.Type: ApplicationFiled: October 17, 2017Publication date: February 8, 2018Inventors: John G.

Patent number: 9481923Abstract: Methods of aluminizing the surface of a metal substrate. The methods of the present invention do not require establishment of a vacuum or a reducing atmosphere, as is typically necessary. Accordingly, aluminization can occur in the presence of oxygen, which greatly simplifies and reduces processing costs by allowing deposition of the aluminum coating to be performed, for example, in air. Embodiments of the present invention can be characterized by applying a slurry that includes a binder and powder granules containing aluminum to the metal substrate surface. Then, in a combined step, a portion of the aluminum is diffused into the substrate and a portion of the aluminum is oxidized by heating the slurry to a temperature greater than the melting point of the aluminum in an oxygen-containing atmosphere.Type: GrantFiled: May 21, 2009Date of Patent: November 1, 2016Assignee: Battelle Memorial InstituteInventors: Jung-Pyung Choi, Kenneth Scott Weil

Patent number: 9283637Abstract: Tools for friction stir welding can be made with fewer process steps, lower cost techniques, and/or lower cost ingredients than other state-of-the-art processes by utilizing improved compositions and processes of fabrication. Furthermore, the tools resulting from the improved compositions and processes of fabrication can exhibit better distribution and homogeneity of chemical constituents, greater strength, and/or increased durability. In one example, a friction stir weld tool includes tungsten and rhenium and is characterized by carbide and oxide dispersoids, by carbide particulates, and by grains that comprise a solid solution of the tungsten and rhenium. The grains do not exceed 10 micrometers in diameter.Type: GrantFiled: January 22, 2013Date of Patent: March 15, 2016Assignee: Battelle Memorial InstituteInventors: Glenn J. Grant, John G.

Patent number: 8424747Abstract: A method for joining two ceramic parts, or a ceramic part and a metal part, and the joint formed thereby. The method provides two or more parts, a braze consisting of a mixture of copper oxide and silver, a diffusion barrier, and then heats the braze for a time and at a temperature sufficient to form the braze into a bond holding the two or more parts together. The diffusion barrier is an oxidizable metal that forms either a homogeneous component of the braze, a heterogeneous component of the braze, a separate layer bordering the braze, or combinations thereof. The oxidizable metal is selected from the group Al, Mg, Cr, Si, Ni, Co, Mn, Ti, Zr, Hf, Pt, Pd, Au, lanthanides, and combinations thereof.Type: GrantFiled: April 5, 2010Date of Patent: April 23, 2013Assignee: Battelle Memorial InstituteInventors: Kenneth Scott Weil, John S. Hardy, Jin Yong Kim, Jung-Pyung Choi

Patent number: 8048587Abstract: An electrically-conductive mesh spacer incorporated into the hydrogen and air gas flow spaces between each anode and cathode and its adjacent interconnect in a fuel cell stack. The mesh is formed of metal strands and is formed into a predetermined three-dimensional pattern to make contact at a plurality of points on the surfaces of the electrode and the interconnect element. The formed mesh spacer is secured as by brazing to the interconnect element at a plurality of locations to form an interconnect, which preserves the pattern during assembly of a fuel cell stack. The height of the formed pattern is greater than the height of a gas flow space after fuel cell assembly, such that the mesh spacer is slightly compressed during assembly of a fuel cell stack. Because the metal mesh is both compliant and resilient, the compressed spacer is continuously urged into mechanical and electrical contact with its electrode over all temperatures and pressures to which the fuel cell assembly may be subjected during use.Type: GrantFiled: November 27, 2002Date of Patent: November 1, 2011Assignees: Delphi Technologies, Inc., Batelle Memorial InstituteInventors: Haskell Simpkins, Karl J. Haltiner, Jr., Subhasish Mukerjee, Kenneth Scott Weil, Dean Paxton

Publication number: 20090016953Abstract: High-temperature air braze filler materials composed of various ternary metal alloys are described. Noble metals (M) are added as a ternary constituent to a silver-copper oxide (Ag—CuOx) system. The silver (Ag) component is directly substituted with the noble metal to form a series of alloys. Addition of the noble metal increases the solidus and liquidus temperatures of the resulting air braze filler metals and increases temperatures under which seals and other sealing components formed from these filler metals can be employed.Type: ApplicationFiled: July 10, 2008Publication date: January 15, 2009Inventors: Kenneth Scott Weil, John S.
