Abstract
The present disclosure relates to a method of incorporating lithium into a coating. One may supply a substrate having a coating containing aluminum ions and immersing the substrate including the coating containing aluminum ions in a water-soluble diketone including lithium for exchange where the ketone carbonyls are separated by at least one carbon atom. This may then be followed by exchanging a portion of the aluminum ions with lithium ions from the diketone solution. Such coatings may have improved chemical resistance.
