Abstract: Disclosed is a system for treating a metal substrate comprising a conversion composition comprising trivalent chromium in an amount of 0.001 g/L to 20 g/L and a sealing composition comprising an ammonium-containing compound. Also disclosed is a method for treating a metal substrate that includes contacting at least a portion of a surface of the substrate with the conversion composition and then contacting at least a portion of the surface of the substrate with the sealing composition. Also disclosed is a substrate obtainable by treatment with the system and/or obtainable by the method of treatment.
