Abstract

L'invention concerne des procédés de traitement et de revêtement d'un substrat métallique ferreux, tel qu'un acier laminé à froid, un acier laminé à chaud, et un acier électrogalvanisé. Ces procédés comprennent la mise en contact du substrat métallique ferreux avec une composition de prétraitement aqueuse comprenant : (a) un composé métallique eu groupe IIIB et/ou IVB ; (b) des ions de phosphate ; et (c) de l'eau. L'invention concerne également des procédés annexes de retrait de fer du bain de prétraitement.
