    摘要: A catalyst carrier body includes at least one housing, a honeycomb body and a passivation layer which includes a multiplicity of separate crystal agglomerations with an averaged height lying in the range of 0.3 to 1.5 μm. Various production methods are proposed which are suitable, in particular, for producing such catalyst carrier bodies. Thus, the formation of the passivation layer takes place by the blending and/or mixing of an adhesive with a passivating substance and subsequently applying the adhesive, or by roughening a region using a blast-cutting manufacturing method with corundum particles being employed as the blasting medium. A barrier is thereby provided in a very simple and cost-effective way which, for example during the formation of brazed connections, prevents the then liquid brazing material from being distributed beyond the desired tying regions as a result of capillary effects.
