Investigation of the corrosion of zinc and polymer-coated steelFunded under: FP4-BRITE/EURAM 3
A model was developed to investigate the corrosive behaviour of galvanized (zinc-coated) steel. Parameters were derived from corrosion tests that simulate outdoor exposure. Two types of defect were considered: delamination resulting from a defect in an intact zinc layer, and delamination resulting from a defect reaching down to the steel surface. Delamination was observed using a Scanning Kelvinprobe, allowing the corrosion potential to be measured below insulating polymer film without touching the surface. The results from this model could also be applied to the substrate as well as the coating system, with the additional parameters of temperature and humidity.
