Abstract

A carrier for abrasion-resistant catalysts having a surface coated with high-fusion oxides, nitrides and/or carbides of at least one transition metal, or boron, of aluminum and/or of silicon or of combination of these compounds. The coating is carried out using physical vapor deposition techniques, such as evaporating coating ion plating or cathode sputtering. The layer thus produced consists of individual structures, such as stems and/or columns having different elevations which together produce a porous layer serving as an intermediate layer for the subsequent deposition of the catalytic material.
