<p>The production of a sheet metal element (1) to form a catalyst body for the catalytic treatment of gas, preferably exhaust gas from combustion engines, where the element corrugates with a corrugated vertex (1d), a metallic core, domains (53) with a coat (29) and exteriors of corrugated vertex with metallic polished domains (55), comprises applying a metallic oxide with a first coat material on the two surfaces of the metal element; removing the first coat material; and applying and developing the second coat material containing catalytic active material on the surface. The production of at least a sheet metal element (1) to form a catalyst body for the catalytic treatment of gas, preferably exhaust gas from a combustion engine, where the element corrugates with a corrugated vertex (1d), a metallic core, domains (53) with core covered with a coat and on exteriors of corrugated vertex with metallic polished domains (55), where at least a corrugate with two surfaces are arranged oppositely comprises applying at least a metallic oxide with a first coat material of the two surfaces of the metal element; removing the first coat material mechanically form the element; and applying and developing a second coat material containing catalytic active material on the surface. Independent claims are included for the following: (1) the production of at least one catalyst body comprising forming the sheet metal element or external sheet metal elements with adjacent sheet metal element layers, where at least a corrugate with corrugated vertices, metallic core and domains with core covered with a coat on the exterior corrugated vertex with metallic polished domains containing sheet metal element layers, which is arranged in corrugated vertex of adjacent layer with a contact domain, such that the metallic domains laying close with the layers are interconnected; (2) the sheet metal element obtained from the above process; and (3) a catalyst body with sheet metal element layers comprising sheet metal element.</p> |
