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.
