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

Publication number: 20080118355Abstract: A turbine blade for turbo-engines as well as a method for manufacturing such a turbine blade is disclosed. According to the task set, the turbine blades should be capable of withstanding high thermal stress and able to maintain an adequate mechanical strength even at raised operating temperatures. The turbine blades are so designed that on the surface of a core element a heat-insulating layer of a metallic open-cell foam is integrally connected to said core element by sintering. The outer contour of the turbine blade is formed with at least one shell element. The shell element comprises a nickel-base alloy, which is also integrally connected by sintering to the open-cell foam which forms the heat-insulating layer.Type: ApplicationFiled: January 13, 2006Publication date: May 22, 2008Applicants: CVRD INCO LIMITED, FRAUNHOFER-GESELLSCAHAFT ZUR FORDERUNG DER ANGEWANDTEN FORSCHUNG E.V.Inventors: Tilo Buttner, Gunnar Walther, Thomas Weissgarber, Michael Schutze, Dirk Naumann, Alexander Bohm
