Abstract

Une couche de conversion ne contenant pas de chrome présentant des caractéristiques de protection contre la corrosion qui sont au moins équivalentes à celles des couches de conversion classiques au chromate peut être formée sur des métaux, particulièrement sur de l'acier laminé à froid, à l'aide d'un liquide acide aqueux séchant sur place dont la valeur de pH se situe entre 0,5 et 5,0 et qui comprend: (A) des anions "fluorométallate" formés par (i) au moins quatre atomes de fluor, (ii) au moins un atome d'un élément sélectionné dans le groupe formé par le titane, le zirconium, le hafnium, le silicium, l'aluminium et le bore, et, facultativement, un ou plusieurs (iii) atomes d'hydrogène ionisables et (iv) atomes d'oxygène; (B) un constituant formé de cations divalents ou tétravalents d'éléments sélectionné dans le groupe formé par le cobalt, le magnésium, le manganèse, le zinc, le nickel, l'étain, le cuivre, le zirconium, le fer, et le strontium suivant une quantité telle que le rapport entre le nombre total de cations de ce constituant et le nombre d'anions du constituant (A) soit au moins égal à environ 1:5 sans toutefois dépasser environ 3:1; (C) un constituant sélectionné dans le groupe formé par les oxyanions inorganiques contenant du phosphore et les anions phosphate ; et (D) un constituant formé d'un polymère d'hydroxy styrène, modifié par substitution sur les anneaux aromatiques des polymères de fractions aminoéthyle substituées, où les substituants (différents de l'atome de carbone qui est directement lié à un anneau aromatique dans le polymère) sur l'atome d'azote amino contiennent conjointement au moins deux atomes de carbone et au moins une fraction hydroxy alors qu'aucun de ces substituants sur l'atome d'azote amino ne contient individuellement plus de la moitié de fractions hydroxyle par rapport au nombre d'atomes de carbone, sauf s'il ne contient qu'un seul atome de carbone.
