COMPOSITION AND PROCESSES OF A DRY-IN-PLACE TRIVALENT CHROMIUM CORROSION-RESISTANT COATING FOR USE ON METAL SURFACES

Corrosion resistant coatings are formed on aluminum by contacting with aqueous solutions containing trivalent chromium ions and fluorometallate ions, the solutions being substantially free of hexavalent chromium. Trivalent chromium films formed on the aluminum surface when tested in 5% NaCl salt spr...
