An open-pored metal body, which is formed having a core layer (A) consisting of Ni, Co, Fe, Cu, Ag or an alloy formed having one of said chemical elements, wherein one of said chemical elements is present in the alloy at more than 25 at %, and a gradated layer (B) is formed on surfaces of the core layer (A), said gradated layer being formed by intermetallic phase or mixed crystals of Al, and a layer (C), which is formed having aluminum oxide, is formed on the gradated layer (B).

Method for producing an open-pored metal body having an oxide layer and metal body produced by said method

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.
