Method and device for the spatially inhomogeneous coating of a honeycomb body and inhomogeneously coated honeycomb body

摘要

The invention relates to a method for coating a support body (1), particularly a honeycomb body that can be penetrated by a fluid, with a coating material (2) which is applied to the support body (1), the spatial temperature distribution of the coating material (2) being inhomogeneous inside the support body (1) during and/or following the application process. Also disclosed are a support body having a spatially inhomogeneous coating thickness and a device for inhomogeneously coating a support body (1). The invention is characterized by the fact that efficient catalysis is ensured and excess coating material is economized in places where said coating material is not needed.
