ABSTRACT:
A metal foil has improved resistance to permanent thermal expansion. This metal foil includes a metal foil substrate and a thin barrier layer on at least one surface of the metal foil substrate. The metal foil can be used in a catalyst assembly to provide a catalyst support having improved resistance to permanent thermal expansion. The catalyst assembly includes a metal foil substrate and a thin barrier layer on at least one surface of the metal foil substrate. A catalyst material is provided on at least a portion of the barrier layer. This invention further relates to a method for reducing permanent thermal expansion of a metal foil. This method includes applying a barrier layer coating to at least one surface of a metal foil substrate. The method further can include the step of applying a catalyst material to at least a portion of the barrier layer.
