Abstract: A composition for application to a metal substrate comprises a metal cation, a metal complexing agent and an aqueous carrier. A substrate or article includes the composition for application to a metal substrate and a coating on the composition. A method of fabricating a substrate comprises applying the composition to a substrate, allowing the composition to dry to form a conversion coating, and applying a coating on the conversion coating.

Abstract: A composition for application to a metal substrate comprises a sol-gel or a silane and a corrosion inhibitor. The corrosion inhibitor comprises a lithium ion and/or an azole compound. A coated substrate includes the composition for application to a metal substrate and a coating on the composition. A method of fabricating a coated substrate comprises applying the composition to a substrate, curing the composition to form a conversion coating, and applying a coating on the conversion coating.

Abstract: Disclosed is a method of treating a substrate. The surface is contacted with a sealing composition comprising a lithium cation; and optionally, with conversion composition comprising a cation of a lanthanide, a Group IIIB, and/or a Group IVB metal. The conversion composition is applied to provide a film on the substrate surface resulting in a level of the lanthanide, Group IIIB metal, and/or Group IV metal thereon of at least 100 counts greater than on a surface of a substrate that does not have the film thereon as measured by X-ray fluorescence (measured using X-Met 7500, Oxford Instruments; operating parameters 60 second timed assay, 15 Kv, 45 μA, filter 3, T(p)=1.5 μs for lanthanides, Group IIIB metals, and Group IVB metals except zirconium; operating parameters 60 second timed assay, 40 Kv, 10 μA, filter 4, T(p)=1.5 μs for zirconium). A substrate obtainable by the methods also is disclosed.

Abstract: Disclosed is a conversion composition containing a trivalent chromium cation in an amount of 0.001 g/L to 20 g/L. Also disclosed is a system for treating a metal substrate that includes the conversion composition and a sealing composition comprising a lithium cation. 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 treating.
