The cleaning, deoxidization, and conversion coating of automotive aluminum alloys with a commercial non-toxic and chrome-free pretreatment system is described in detail. The results of paint adhesion and filiform testing with powder coatings, solvent and water borne epoxies and various urethane coatings is presented along with comparison data for chrome and other non-chrome systems. Neutral salt-spray data is presented. In addition, scanning electron micrographs of treated surfaces are shown along with data on the physical and chemical composition of the surfaces.
