Abstract (en)

[origin: WO2016120669A1] The invention relates to a method for the production of a coated metal sheet, comprising the application of an aqueous solution containing an amino acid, and associated use in order to improve corrosion resistance. More specifically, the invention relates to a method for the production of a metal sheet (1), comprising at least the steps of: providing a steel substrate (3) having two faces (5), of which at least one is coated with a metal coating (7) including at least 40 wt.-% zinc; and applying an aqueous solution containing an amino acid to the outer surface (15) of the metal coating (7). The invention also relates to the resulting sheet.
