Abstract

The invention relates to a method for treating an anodized aluminum surface (11) having pores (13), nanoparticles (14) being introduced into said pores. The invention is characterized in that the nanoparticles are dispersed in a liquid dispersant before they are introduced and are subjected to a subsequent treatment after their introduction. Energy is supplied to the pores (13), resulting in a reaction of the nanoparticles (14) with other components of the dispersion so that at least the surface thereof is changed. In this manner, for example silicate, especially boron silicate, nanoparticles (14) can be produced that adhere well to the pores (13). Said nanoparticles may e.g. be used to receive a catalyst material in the pores.
