Process for the production of coated metal sheets involving the application of aqueous solutions containing amino acids and related uses for improving tribological properties

摘要

The present invention is a method for producing a metal plate (1), comprising at least: a steel substrate (3) having two faces (5), wherein at least one face of the two faces (5) is at least Providing a steel substrate (3) coated with a metal coating (7) comprising 40% by weight of zinc, applying an aqueous solution comprising amino acids to the outer surface (15) of the metal coating (7) And a metal plate that can be obtained.
