Title (EN) METHODS FOR PRODUCING A PRE-LACQUERED METAL SHEET HAVING ZN-AL-MG COATINGS, AND CORRESPONDING METAL SHEET
(FR) PROCÉDÉS DE RÉALISATION D'UNE TÔLE PRÉLAQUÉE À REVÊTEMENTS ZnAlMg ET TÔLE CORRESPONDANTE
Abstract: front page image
(EN)The method comprises the following steps: providing a steel substrate (3) having two faces (5) that are coated by quenching the substrate (3) in a bath, altering the magnesium hydroxide or magnesium oxide layers formed on the outer surfaces (15) of the metal coatings (7) by applying an acid solution, optionally a conversion solution, having a pH of between 1 and 2 and/or mechanical stress, and painting the outer surfaces (15) of the metal coatings (7).
(FR)Ce procédé comprend des étapes de : - fourniture d'un substrat (3) en acier présentant deux faces (5) revêtues par trempe du substrat (3) dans un bain, - altération de couches d'oxyde de magnésium ou d'hydroxyde de magnésium sur les surfaces extérieures (15) des revêtements métalliques (7) par application dune solution acide, éventuellement de conversion avec un pH compris entre 1 et 2, et/ou d'efforts mécaniques, - mise en peinture des surfaces extérieures (15) des revêtements métalliques (7).
