    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, 15Kv, 45μA, filter 3, T(p) = 1.5μs for lanthanides, Group IIIB metals, and Group IVB metals except zirconium; operating parameters 60 second timed assay, 40Kv, 10μA, filter 4, T(p) = 1.5μs for zirconium). A substrate obtainable by the methods also is disclosed.

    Abstract: Disclosed is a method of making a treatment composition. A lithium cation and carbon dioxide are combined in an aqueous medium to form the treatment composition comprising lithium carbonate in situ. Also disclosed is a system and method for maintaining a treatment bath formed from a treatment composition comprising lithium carbonate. Carbon dioxide and/or a lithium salt are supplied to the bath in an amount sufficient to maintain the pH of the treatment bath at 9.5 to 12.5, lithium in an amount of 5 ppm to 5,500 ppm (calculated as lithium cation) and carbonate in an amount of 15 ppm to 25,000 ppm (calculated as carbonate) based on total weight of the treatment bath. Sustrates treated with the composition, system and method also are disclosed.
