Abstract
L'invention concerne principalement l'utilisation d'une solution aqueuse de traitement contenant des ions sulfates so42-à une concentration supérieure ou égale à 0,01 mol/l, pour traiter une tôle comprenant un substrat en acier revêtu sur au moins une de ses faces d'un revêtement comprenant au moins du zinc et du magnésium, en vue de réduire le noircissement ou le ternissement de la tôle lors de son stockage. L'invention concerne également la tôle traitée par une telle solution.
