摘要
This invention relates to a composition and method for coating aluminum in order to improve both corrosion resistance and paint adhesion. By using very low concentrations of hexavalent chromium ions, phosphate ions and fluoride ions in the coating composition, the characteristics of the treated aluminum surfaces are improved, while process waste disposal problems are minimized.
