Zusammenfassung:	The invention relates to 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 graded layer (B) is formed on surfaces of the core layer (A), said graded 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 graded layer (B). L'invention concerne un corps métallique à pores ouverts, qui est formé avec une couche centrale (A) constituée de Ni, Co, Fe, Cu, Ag ou d'un alliage formé avec l'un de ces éléments chimiques. Un desdits éléments chimiques est contenu à plus de 25 % at. dans l'alliage. Une couche graduée (B), qui est formée avec une phase intermétallique ou des cristaux mixtes de Al, est réalisée sur des surfaces de la couche centrale (A), et une couche (C), qui est formée avec de l'oxyde d'aluminium, est réalisée sur la couche graduée (B).
