Abstract
The invention concerns a method for producing an anticorrosive coating for metal parts, free of chromium and chromium-based derivatives and in particular hexavalent chromium, preferably to be applied in thin layers while providing highly efficient protection. Said coating consists of the synergistic association of a first metal zinc layer and one or several coating layers obtained by using an aqueous composition containing a particulate metal, an appropriate solvent, a thickening agent and a binder consisting of a silane.
