  • Patent number: 10596556
    Abstract: A metallic foam body containing an alloy skin which is up to 50 ?m thick can be obtained by a process including (a) providing a metallic foam body comprising a first metallic material; (b) applying a second metallic material which contains a first metallic compound that is leachable as such and/or that can be transformed by alloying into a second metallic compound that is leachable and different from the first metallic compound on a surface of the foam body (a), by coating the metallic foam body with an organic binder and a powder of the second metallic material; (c) forming a skin on foam body (b) by alloying the first and the second metallic material; and (d) leaching out with a leaching agent at least a part of the first and/or the second metallic compound.

  • Patent number: 9346240
    Abstract: 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.

  • Patent number: 8758675
    Abstract: 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.

  • Publication number: 20080118355
    Abstract: 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.
