| abstract |
The invention describes a process for the production of a coating ( 6 ) on the basis of at least one material selected from a group comprising silicon, germanium, and the oxides SiO x or GeO x of these elements, whereby these are doped where applicable and produced specifically amorphised, on at least a subsection of a surface ( 3 ) of a metallic substrate ( 2 ), whereby the concentration of nitrate is increased in the substrate ( 2 ) where applicable prior to precipitation of the coating ( 6 ) at least in the area of the subsection. This subsection is subjected to oxidation prior to precipitation of the coating ( 6 ). |
