Abstract
An article includes a substrate, a functional coating deposited over at least a portion of the substrate, and a protective (barrier) coating deposited over at least a portion of the functional coating. The barrier coating is stable to oxygen-containing gases and limits the transmission of oxygen-containing gases to materials over which it is deposited when subjected to conditioning steps such as heating, bending, and/or tempering.
