Abstract: The disclosure concerns a process for producing a sol-gel coating on a surface of a component made of aluminum or of an aluminum alloy that is to be coated, comprising the following steps: anodization of the surface through the application of an electrical voltage over a particular time period so as to form an anodized layer on the surface; and deposition of a sol-gel coating on the surface. In doing so, the voltage applied for purposes of anodizing is, by way of a particular potential gradient, continuously increased in the direction of a holding voltage that is maintained throughout the rest of the anodization time, in particular up to the holding voltage. The disclosure furthermore concerns a component made of aluminum or an aluminum alloy.

Abstract: A distance device bridges a free space between a carrier part and a roof body for fastening a roof luggage rack, such as a roof rail, a roof strip or the like, on a vehicle roof by a threaded screw, with a support part and a counter support part. The support part and counter support part are held together by a threaded connection and can be adjusted relative to each other in order to set a bridging length. The support part or counter support part is carried along by a rotationally engaging connection with the threaded screw when it is screwed into a counter thread of the roof luggage rack or carrier part as far as a contact position with the carrier part or the roof body. The rotationally engaging connection has a plastic carrier into which the thread of the threaded screw is/has been screwed for carrying along with frictional resistance.

Abstract: 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.
