Nitrate ions, which are known as efficient inhibitors for the corrosion of aluminum, have been shown to become very aggressive in pitting of 2024 aluminum alloy in specific conditions. Plotting potentiokinetic curves and immersion tests revealed strong dissolution of 2024 alloy in nitrate solutions with or without chloride ions. Scanning electron microscopy observations showed that pitting of 2024 alloy mainly occurred on the intermetallic particles. Nitrate ions caused the dissolution of… CONTINUE READING
