Abstract
ABSTRACTThe influence of different locations on copper corrosion with different external electric fields under a chloride-containing thin electrolyte layer was studied using polarisation curve measurement and surface analysis techniques. The results indicated that, under an external direct current electric field, the anodic current densities near the positive plate were smaller than that near the negative plate, while the cathodic current densities near the positive plate were larger than that near the negative plate. However, at different locations in an external alternating current electric field, the anodic current densities were little change, while the cathodic current densities were obviously different.
