Influence of acetic acid on corrosion behavior of 1100 pure aluminum

Abstract

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.
