Surface observation and electrochemical measurements were carried out to clarify the influence of acetic acid on corrosion behaviors of industrially pure aluminum alloy 1100. The consideration of the potential-pH-pOAc diagram and polarization analysis reveal that coexistence of citric acid and chloride ions will severely pitting-attack aluminum alloy 1100.

The corrosion behaviors of the four kinds of Al-Cu alloys with different copper contents ranging from 0.36-1.30% were investigated in terms of the corrosion weight loss, micromorphology observations and measurements of the corrosion potentials. Increasing the content of copper in aluminum results in decreasing the corrosion resistance of aluminium. It is shown that the copper in solid solution has less effect on the corrosion resistance than the copper as intermetallic phases of CuAl2.

Behavior of dry corrosion which is electrochemical reaction between Al-Mg-Si alloy 6063 and ethanol in gasoline has been investigated. Dry corrosion has not been observed in E3 (3% ethanol) and E10 (10% ethanol) at room temperature, but observed in E3 and E10 when a small amount of aluminum chloride had been added to them at room temperature. The higher solution temperature is, the more often the dry corrosion occurs. Dry corrosion has also been observed in the above solution environments in which 0.1% and 1% water contained. Occurrence of dry corrosion was detected by the area polarization method, which revealed that initiation and propagation of the dry corrosion corresponds to the decrease of anodic polarized resistance of 6063.
