摘要：

The effects of Cl-, Cu2+ and Fe3+ ions and their combinations on the corrosion behaviour of aluminium alloy 6063 (AA6063) in ethylene glycol and water solutions at 50 degrees C were investigated by electrochemical and immersion methods. Cl- resulted in pitting corrosion of the alloy. In the Cl--free solutions, Fe3+ was prone to accelerate uniform corrosion, while Cu2+ tended to accelerate pitting corrosion. Severe pitting corrosion of AA6063 was observed in the cases of Cl- combined with Cu2+ or Fe3+, especially in the case of Cl- combined with Cu2+ and Fe3+ ions.
