Abstract: Methods for treating a substrate are disclosed. The substrate is deoxidized and then immersed in an electrodepositable pretreatment composition comprising a lanthanide series element and/or a Group IIIB metal, an oxidizing agent, and a metal-complexing agent to deposit a coating from the electrodepositable pretreatment composition onto a surface of the substrate. Optionally, the electrodepositable pretreatment composition may comprise a surfactant. A coating from a spontaneously depositable pretreatment composition comprising a Group IIIB and/or Group IVB metal may be deposited on the substrate surface prior to electrodepositing a coating from the electrodepositable pretreatment composition. Following electrodeposition of the electrodepositable pretreatment composition, the substrate optionally may be contacted with a sealing composition comprising phosphate and a Group IIIB and/or IVB metal. Substrates treated according to the methods also are 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. Substrates treated with the composition, system and method also are disclosed.
