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 present invention relates to a catalyst support body () with a longitudinal axis () comprising a honeycomb body () and a housing (), wherein the honeycomb body () consists of at least three metal layers () arranged one above the other, which are wound with their end surfaces in each case starting from a common centre into layers lying one above the other in the form of a spiral and are secured in the sleeve of the housing (), wherein the metal layers consist of metal-foam layers, and wherein a metal-foam layer developed as a corrugated sheath () is arranged between two planar metal-foam layers (), wherein attachment sections () on the outside of the corrugated sheath () connect it to the planar metal-foam layers ().
