Abstract (en)
[origin: WO2015150387A1] The invention relates to a method for anti-corrosion treatment of components produced from aluminum, comprising a pre-treatment stage and subsequent painting. The passivation of the pre-treatment stage includes the bringing of the components into contact with an acidic aqueous composition based on water soluble compounds of the elements Zr and/or Ti. Pickling and passivation are coordinated with each other such that a re-dosing of active components of the passivation solution can occur in substantial parts from the pickling solution.
