| 摘要 |
The invention relates to a method for applying a washcoat dispersion (3) to a honeycomb structure (1) that is provided with channels (2). The washcoat dispersion (3) is preferably a substrate material (13) evenly distributed in a substrate fluid and comprising a mixture of stabilized, high-surface aluminum oxide of the transition group elements and at least one promoter oxide. The inventive method is further characterized in that the honeycomb structure (1) is contacted with the washcoat dispersion (3), the washcoat dispersion (3) being induced to vibrate at least while it is applied, thereby preventing the washcoat dispersion from prematurely gelling and ensuring a uniform washcoat thickness in the channels.
