Patent

CA 2754138

The invention relates to a method for coating metal surfaces, in particular surfaces of wheels made of an aluminum alloy, in a multi-step method, wherein the metallic surfaces are first contacted with an aqueous composition predominantly contai-ning silane/silanol/siloxane/polysiloxane and thereafter contacted with an aqueous composition predominantly containing at least one phosphonic compound, wherein the phosphonic compounds are selected from among compounds of the type XYZ, wherein Y is an alkyl group having 8 to 16 C atoms, wherein a silane coating and a phosphonate coating are formed successively.

L'invention concerne un procédé de revêtement de surfaces métalliques, en particulier de surfaces de roues en alliage d'aluminium, suivant un processus en plusieurs étapes, caractérisé en ce que les surfaces métalliques sont mises en contact tout d'abord avec une composition aqueuse renfermant principalement du silane/silanol/siloxane/polysiloxane, puis avec une composition aqueuse renfermant principalement au moins un composé phosphonique, en ce que les composés phosphoniques sont sélectionnés à partir de composés du type XYZ, où Y désigne un groupe alkyle de 8 à 16 atomes de C, et en ce qu'ensuite un revêtement au silane et un revêtement au phosphonate sont formés.
