Objective
The main aim of this project is to improve our knowledge of the fundamental mechanisms in the initiation and propagation of corrosion on pre-painted galvanized sheet beneath the paint layer. Laboratory studies will be made of: - the effect of degreasing treatment on the chemical composition of the surface and the reactivity of the substrate, the adhesion of the primer and resistance to corrosion by delamination; - metallographic cross-sectional examination of the different types of degradation due to atmospheric corrosion as a result of scratches, cracks, grooves and dents; - a qualitative and quantitative description of the mechanisms of corrosion and a simulation of the major stages in degradation by means of suitable electrochemical methods.
