Abstract

Gegenstand der Erfindung ist ein Verfahren zum Behandeln einer anodisch oxidierten Aluminiumoberfläche (11) mit Poren (13), wobei in diese Poren Nanopartikel (14) eingebracht werden. Erfindungsgemäß ist vorgesehen, dass die Nanopartikel vor dem Einbringen in einem flüssigen Dispersionsmittel dispergiert werden und nach dem Einbringen einer Nachbehandlung unterworfen werden. Hierbei erfolgt ein Energieeintrag in die Poren (13), die zu einer Reaktion der Nanopartikel (14) mit weiteren Bestandteilen der Dispersion führt, so dass zumindest deren Oberfläche umgewandelt wird. Auf diesem Weg lassen sich beispielsweise hervorragend in den Poren (13) haftende Nanopartikel (14) aus Silikaten, insbesondere Borsilikat, herstellen, wobei diese Nanopartikel beispielsweise zur Aufnahme eines Katalysatormaterials in den Poren dienen kann.
