摘要：

Zinc-coated steel strip is painted in coil-coating plants in order to improve corrosion resistance and to provide a decorative surface. We have used Auger and x-ray photoelectron spectroscopy to characterize the conversion costing formed during pretreatment of hot dip zinc-coated steel prior to coil coating. The pretreatment process includes alkaline cleaning of the strip, alkaline oxidation and a chromic acid after-rinse treatment. The composition and the chemical state of the surface have been examined after the different pretreatment steps.
