Objectif
Steel sheets assembled using lap joints are prone to suffer accelerated corrosion processes at the joints: premature deterioration of the finishing paint film and accelerated metallic corrosion at the base (steel and metallic coating). There is relatively little research concerning this topic, particularly into the basic understanding of primary factors involved.
The following objectives will be pursued: - to identify the most influential intrinsic factors related to the system (steel/metallic coating/organic film); - testing panels for accelerated evaluation and electrochemical sensors. Once these factors have been established the methodology for optimal selection of the substrate, pre-treatments and organic films will be defined. The research will be mainly focused on industrial systems currently in use: zinc, aluminium-zinc, zinc-nickel. Electrochemical techniques will be completed with conventional atmospheric outdoor tests, accelerated tests in climatic chambers and surface analysis techniques.
