OFFENZELLIGE KERAMIK- UND/ODER METALLSCHÄUME MIT RAUER UMHÜLLENDER OBERFLÄCHE UND EIN VERFAHREN ZU IHRER HERSTELLUNG
The invention pertains to the field of material sciences and relates to open-cell ceramic and/or metal foams, such as can be used, for example, as catalyst carriers. The problem of the present invention is to specify ceramic and/or metal foams through which an improved adherence to coatings is achieved. The problem is solved by foams, wherein the enveloping surfaces of the ligaments are composed of a material having a rough surface and/or are coated with a rough layer. The problem is further solved by a method, wherein a suspension is produced from a monomodal powder or a bimodal powder mixture, an open-cell polymer foam is coated with said suspension, and then the green or sinter body is coated with a suspension of a monomodal ceramic and/or metal powder and sintered. The task is also solved by a method, wherein an open-cell polymer foam is coated with a suspension of ceramic and/or metal powders having a monomodal particle size distribution and sintered.
