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

摘要

A kind of method of the present invention is used for coating supporter (1), especially honeycomb ceramics those can be by fluid, it is applied to a supporter (1) with coating material (2), spatial temperature distribution is that non-uniform coating material (2) applies process during and/or after supporter (1). Also disclosing a kind of supporter has spatial non-uniform thickness of coating and device for unevenly coating supporter (1). The invention is characterised in that following fact: efficient catalytic ensure that excess coating material energy conservation is not needed in the coating material suitably.
