Abstract
A housing for a honeycomb body includes a jacket tube with an inner wall surface. The jacket tube has a passivation layer in at least one section of the inner wall surface in order to deliberately modify a connection to the honeycomb body by joining. A method for the production of a catalyst carrier body with a honeycomb body and a housing according to the invention are also indicated. A catalyst carrier body produced in this way reduces thermal stresses between the honeycomb body and the jacket tube and, in particular, ensures a reliable brazing process during production, even in a vacuum.
