Partial pigmentation of a coating layer to prevent interference on aluminum components or components comprising aluminum

摘要

A method for treating the surface of aluminum components or components comprising aluminum includes anodizing the surface. Anodizing includes introducing at least one pigmenting substance, particularly fully pigmenting substance, into depressions or pores open toward the surface of a comb or pore structure of the surface created by the anodizing process, and/or introducing oxidizable substances into depressions or pores open toward the surface of a comb or pore structure of the surface created by the anodizing process and oxidizing these substances. The method further includes applying a ceramic thin-film coating or siliceous sol-gel coating onto the surface. The ceramic thin-film coating or the sol-gel coating comprises a pigment particularly serving refraction purposes.

1. A method for treating a surface of aluminum components or components comprising aluminum, the method comprising:
anodizing the surface to create a pore structure on the surface; compacting the pore structure of the surface to create compacted pores such that the compacted pores constrict but do not close; introducing at least one substance into the compacted pores, the at least one substance including a first pigment; and applying a coating selected from a group including a ceramic thin-film coating and a siliceous sol-gel coating onto the surface, the coating including a second pigment.
