Publication number: 20200276644Abstract: The invention relates to a method for producing open-pore molded metal bodies which have a modified surface. The surface of an open-pore molded metal body said molded body being used as a semi-finished product, is coated with particles of a chemical compound of a metal on particles of the metal which can be reduced or thermally or chemically decomposed in a thermal treatment. After the coating process, at least one thermal treatment is carried out, in which the produced metal particles are connected to the surface of the semi-finished product and/or adjacent produced particles via sintered necks or sintered bridges such that the specific surface area of the obtained open-pore molded body is increased to at least 30 m2/l and/or at least by a factor of 5 in comparison to the starting material of the uncoated metal semi-finished product.Type: ApplicationFiled: September 14, 2018Publication date: September 3, 2020Applicants: Alantum Europe GmbH, Fraunhofer-Gesellschaft zur Foerderung Der Angewandten Forschung e.V.Inventors: Tilo BUETTNER, Gunnar WALTHER, Hans-Dietrich BOEHM, Thomas WEISSGAERBER, Bernd KIEBACK, Christian MUELLER, Robin KOLVENBACH, Lars TORKUHL

Publication number: 20200263306Abstract: A method for producing open-pored molded bodies made of a metal. The surface of the metal open-pored molded body being used as a semi-finished product, is coated with particles of the same metal with which the semi-finished product is made or with particles of a chemical compound of the metal the semi-finished product is made, wherein the compound or particles can be reduced or thermally or chemically decomposed in a thermal treatment. After the coating process, a thermal treatment in a suitable atmosphere is carried out, in which the particles are connected to the surface of the semi-finished product and/or adjacent particles such that the specific surface area of the obtained open-pore molded body is increased to at least 30 m2/l and/or at least by a factor of 5 in comparison to the starting material.Type: ApplicationFiled: September 14, 2018Publication date: August 20, 2020Applicants: Alantum Europe GmbH, Fraunhofer-Gesellschaft zur Foerderung der Angewandten Forschung e.V.Inventors: Tilo BUETTNER, Gunnar WALTHER, Hans-Dietrich BOEHM, Thomas WEISSGAERBER, Bernd KIEBACK, Christian Immanuel MÜLLER, Robin KOLVENBACH, Lars TORKUHL

Patent number: 9346240Abstract: Disclosed are an open-porous metal foam and a method for manufacturing the same. An open-porous metal foam according to an exemplary embodiment of the present invention is made of an iron-based alloy including 15 wt % or more of chrome and 5 wt % or more of aluminum. The open-porous metal foam is a semi-product that is formed of iron or the iron-based alloy that does not include chrome and aluminum or includes a smaller amount of chrome and aluminum in the powder when manufacturing, and the surface and the open pore thereof are uniformly coated with the powder of the iron-chrome-aluminum alloy and the organic binding agent. When heat treatment is performed under a reduction atmosphere, sintering is performed.Type: GrantFiled: August 28, 2013Date of Patent: May 24, 2016Assignees: ALANTUM, FRAUNHOFER GESELLSCHAFT ZUR FORDERUNG DER ANGEWANDTEN FORSCHUNG E.V.Inventors: Gunnar Walther, Burghardt Klöden, Juliane Böhm, Tilo Büttner, Thomas Weissgärber, Bernd Kieback, Arne Boden, Hans-Dietrich Böhm, Hyuntae Kim, James Choi, Myungjoon Jang, Alexander Böhm, Stefan Fröhlich, Winfried Dölling

Patent number: 8758675Abstract: The invention relates to a method for fabricating an open-porous metal foam body with a nickel base alloy, to a metal foam body fabricated this way as well as advantageous applications for the separation of specific components and pollutants from fluid flows. On the occasion, according to the set object open-porous metal foam bodies which have improved mechanical properties, and in addition an enlarged specific surface and/or increased surface roughness are to be provided. During fabricating it is proceeded such that an open-porous base foam body made of nickel or a nickel base alloy is coated with a liquid binding agent. Subsequent to this, a mixture of a powdery nickel base alloy and an organic component the temperature of phase transformation of which is at least 30 degrees centigrade from its solid phase to the liquid phase is deposited. The temperature should then be below the respective temperature of phase transformation.Type: GrantFiled: February 24, 2006Date of Patent: June 24, 2014Assignees: Alantum Corporation, Fraunhofer Gesellschaft zur Forderung der Angewandten Forschung E.V.Inventors: Alexander Böhm, Dirk Naumann, Tilo Büttner, Gunnar Walther, Shadi Saberi, Lloyd Timberg
