摘要：
The effect of nitrate on the corrosion behavior of 7075-T651 aluminum alloy in an acidic NaCl solution is investigated by electrochemical investigation and morphology characterization. Localized corrosion initiated from intermetallic particles could be observed in the solution with and without NaNO3. The nitrate plays a controversial role in the corrosion of 7075-T651 aluminum alloy. It could enhance the performance of passive film and reduce the probability of pitting corrosion initiation. However, the pitting corrosion would be promoted by nitrate, once stable pitting corrosion is initiated.
