Lifetime Prediction of Organic Coating/Metal System.

Abstract

The objective of this project is to develop a lifetime model which takes into account the corrosion susceptibility of metal substrates, the properties of organic coatings and the corrosivity of the environment. The results obtained during the first year include the characterization of steel surfaces which had been subjected to different pretreatment methods using surface chemistry analysis (AES, XPS, SEM), surface energetics analysis, and surface mapping. The deposition kinetics and surface morphology of zinc phosphate coatings on steel surfaces with different pretreatment have been studied with preliminary analysis using a.c. impedance techniques. These results provide a quantitative characterization of the substrate and provide input for a lifetime prediction model of polymer coated metal. (Author)
