Abstract

Process for the formation of protective coatings on a zinc-containing surface, characterized in that a clean zinc surface is placed in contact with a coating composition comprising an aqueous, acidic solution, substantially free of silver ions, containing ions of exavalent chromium, fluoride ions and at least 0.01%, based on the weight of the aqueous solution, of an activator formed by at least one ion chosen from tungsten, molybdenum, vanadium and uranium, the amounts of said ions in the respective metals, said solution is maintained in contact with the surface for a sufficient length of time to form the desired coating, the surface thus provided with a coating is removed from contact with the solution and then the surface is laid thus provided with a coating in contact with a rinsing composition comprising an aqueous solution containing ions of cro Exavalent.
