Abstract
An aluminum alloy article is cleaned to remove oxides and organic matter from a coatable surface, coated with a composition comprising an organic resin and a fluorine compound, and then heated to an elevated temperature to decompose the organic resin and at least a portion of the fluorine compound. After heating the coated surface is left with a protective oxyfluoride film that prevents blistering and hydrogen pickup and promotes hydrogen degassing from the article.
