Notes:
The present work is part of a broader investigation of the effects of additives in zincphosphate (ZPO) coating solutions that are designed for specific applications to Al and its alloys.ZPO conversion coatings improve the corrosion resistance of the Al substrate and increase theadhesion of paint. Coatings formed on 2024-T3 aluminum alloy, after dipping in ZPO coatingbaths containing Mn2+, have been studied by X-ray photoelectron spectroscopy (XPS), SEM, andscanning Auger microscopy (SAM). Variations are observed in coating morphology andcomposition as the amount of Mn2+ in the coating solution increases through the 0 to 2500 ppmrange. Adhesion tests give information on the relative strength of the coating-substrate interactionat different microstructural areas
