Abstract
A coating composition is disclosed that includes a binder, a tri-valent chromium solid, and a stabilized oxidizing agent. The coating composition is used in a method to protect a surface of a metallic article, such as an aluminum article. The tri-valent chromium solid forms a soluble hexavalent chromium compound as a result of reaction with the oxidizing agent when activated in the presence of a corrosive environment. The released water soluble hexavalent chromium migrates to coating defects to protect the metallic article.
