Abstract

The corrosion behaviour of an assembly between an AA1370 cable and a pure copper connector for wiringharnesses was studied in neutral chloride and sulphate containing solution. Electrochemical impedancemeasurements showed that the corrosion behaviour of the cable was controlled by the ingress of the elec-trolyte inside cable cavities. Further, local impedance measurements were performed on two assemblycross-sections, i.e. with and without cavities in the aluminium cable. The results provided evidence forboth the galvanic coupling between aluminium and copper and the presence of cavities in the aluminiumcable as relevant explanations for the corrosion behaviour of the assembly
