Abstract
A method for anti-corrosion treatment of components produced from aluminum, comprising a pre-treatment stage and subsequent painting. The pre-treatment stage includes steps of pickling and passivation wherein passivation of the components includes contacting them with an acidic, aqueous composition based on water-soluble compounds of the elements Zr and/or Ti. The pickling and passivation are coordinated with each other so that a re-dosing of active components of the passivation solution can occur in substantial parts from the pickling solution.
