摘要
The invention relates to the field of materials science and to open-cell ceramic - and / or metallic expanded material components, such as, for example, they can be used for the catalyst carrier.The object of the present invention consists in specifying of ceramic - and / or of the metallic expanded material components, as a result of which improved adhesion to coatings is achieved.The object is achieved by foams, in which the enveloping surfaces of the webs of a material having a rough surface and / or are covered with a rough layer.The object is furthermore achieved by a method in which from a monomodal powder or a bimodal powder mixture used to prepare a suspension, an open-cell polymer foam and then coated with the green - or sintered body with a suspension of a monomodal ceramic - and / or metal powder is coated, and sintered.The object is also achieved by a method in which an open-cell polymer foam with a suspension of ceramic - and / or metal powders with a monomodal particle size distribution are coated, and sintered.
