A method of manufacturing a catalyst material includes the steps of: providing a body having an open-porous foam structure and comprising at least a first metal or alloy; providing particles, each of which particles comprising at least a second metal or alloy; distributing the particles on the body; forming a structural connection between each of at least a subset of the particles and the body; and forming an oxide film on at least the subset of the particles and the body, wherein the oxide film has a catalytically active surface.

Catalyst material and method of manufacturing the same

A metallic foam body containing an alloy skin which is up to 50 &#x3bc;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.

Surface modified metallic foam body, process for its production and use thereof

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. In this case, the metal foam body that is formed of the iron-chrome-aluminum alloy is obtained by compensating concentrations of alloy elements between the semi-product and the powder by diffusion, and a content of chrome and aluminum in the metal foam is smaller than a content of chrome and aluminum included in a starting alloy of the used powder.

Open-porous metal foam body and a method for fabricating the same

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. By means of thermal treatment the binding agent and the organic component are expelled, a portion of the powder particles is sintered, and a further portion of the powder particles is connected with the surface of the base foam body in a material-fit manner via sintering bridges.
