Abstract

Procedure for the surface treatment of metals, characterized by comprising the steps of coating the surface of a metal, selected from the group consisting of zinc and its alloys, with a mixed solution of chromic acid and colloidal silica and drying the applied solution, to form a thin film on the surface.
