PROBLEM TO BE SOLVED: To provide a method for coating a metal surface with a polymer layer in order to prevent corrosion from occurring on the metal surface without using a chromic electrolyte solution. SOLUTION: According to the invention a metal surface is coated with a polymer layer for inhibiting the corrosion of the surfaces by the subsequent steps of: contacting the metal surface with a solution comprising an acid, wherein the acid comprises phosphor in oxidation state +3 and an alkyl group, wherein the alkyl group can interact with a plastic monomer or polymer, and contacting the acid solution treated metal surface of step with a solution comprising monomeric or polymeric resins or a mixture of monomeric and polymeric resins, wherein the monomeric and/or polymeric resins are able to interact with a carboxylic group of the acid used in the first step. By the subsequent steps an adherent sealing layer is built on the metal surface. COPYRIGHT: (C)2007,JPO&INPIT
