METHOD AND DEVICE FOR THE SPATIALLY INHOMOGENEOUS COATING OF A HONEYCOMB BODY AND INHOMOGENEOUSLY COATED HONEYCOMB BODY

摘要

A process for coating a carrier body, in particular a honeycomb body through which a fluid can flow, with a coating material which is applied to the carrier body, provides a spatial temperature distribution of the coating material in the carrier body being inhomogeneous during application and/or after application. A carrier body has a spatially inhomogeneous coating thickness and an apparatus is provided for the inhomogeneous coating of a carrier body. Efficient catalysis is ensured and superfluous coating material is saved at locations where it is not required.
