Descrizione

A method for the treatment of metal surfaces comprising in succession: - a step of depositing a coating of metal oxide, in which on a metal surface a sol is deposited made from a colloidal suspension in water of one or more metal alkoxides M(OR)n in the presence of an acid catalyst, in which: M is comprised in the group consisting of Al, Ti, Si, Y, Zn, Zr; R is a linear or branched aliphatic chain C1-C4; - a step of consolidation, wherein the coating is subjected to a temperature between 150 DEG C and 900 DEG C; - a step of functionalization, in which the coating is treated with boiling water and/or steam for the realization of hydroxyl groups; - a second step of consolidation, wherein the coating is subjected to a temperature between 150 DEG C and 900 DEG C, and - a step of fluorination, wherein the coating is treated with a fluorinated compound.
