Abstract
Corrosion-inhibiting coatings (i.e., pretreatments) are used in the production of painted aluminum surfaces. This paper compares the surface compositional changes as they occur during the chemical coating of 3003 aluminum alloy. Several commercial coatings are examined and chemically identified by a combination of Auger electron spectroscopy, X-ray photoelectron spectroscopy, scanning electron spectroscopy, Fourier transform infrared spectroscopy, and X-ray energy dispersive spectroscopy. Corrosion-inhibiting coatings are classified by their chemical composition. Commercial pretreatments include at least two types of coatings: (a) those which produce a chemically different protective layer without regard to effluents, and (b) those designed to decrease environmental problems (i.e., cyanide-free), while still providing a protective layer. Finally, the corrosion resistance of pretreatments plus a commercial coil coating acrylic paint under accelerated test conditions has been determined.
