摘要：

Corrosion behaviour of pure aluminium galvanically connected to metallic copper or in the presence of Cu2+ ions was investigated by electrochemical measurements in Na2SO4 and Na2SO4 + NaCl test solutions. It has been found that in aerated Cl- ion containing solutions pitting corrosion of aluminium emerged immediately, while in the absence of oxygen this process was less violent. Effect of passivating pre-treatment of aluminium surface on corrosion behaviour Cu-Al bimetallic system is also demonstrated. (c) 2007 Elsevier Ltd. All rights reserved.
