More Information
Summary: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).
