Abstract

The present invention relates to a method for the corrosion-protective pretreatment of metal components, which at least partially comprise metal surfaces made of iron, using a chromium-free aqueous treatment solution, which contains fluoro-complexes of zirconium and/or titanium and phosphate ions in a specific ratio range to one another, and a metal component which is pretreated accordingly, and the use thereof for the application of further corrosion-protective coatings and/or lacquer systems. The method is suitable in particular as a pretreatment for electrophoretic painting of metal components, which are provided in the form of non-closed hollow bodies.
