Abstract (en)
[origin: WO2014056944A1] The invention relates to a process for producing a sol-gel coating on a surface to be coated of a component composed of aluminium or an aluminium alloy, which comprises the steps: anodization of the surface by application of an electric potential over a particular anodization time in order to form an anodization layer on the surface; and formation of the sol-gel coating on the surface. It is provided that the potential applied for anodization at the beginning of the anodization time is increased continuously with a particular potential gradient in the direction of a hold potential maintained over the remainder of the anodization time, in particular up to the hold potential. The invention further relates to a component composed of aluminium or an aluminium alloy.
