Abstract A real-time monitor method based on Electrochemical Noise (EN) was set up to study the atmospheric corrosion of aluminum alloy. The electrolytic cell was designed and made accordingly. Inshore, oceanic atmosphere and contaminative industrial atmosphere with neutral pH value, constant temperature and humidity were simulated.Using the established method atmospheric corrosion of the aluminum alloys LY12CZ and LC4CS was studied. The electrochemical noise resistance Rn and the slopes K of the potential power density spectrum (PDS) were gotten in EN test. The corrosion behavior of aluminium alloy in simulated atmosphere, and influence of Cl—、NO3— and SO42— in corrosion process of the aluminium alloys (LY12CZ and LC4CS) were studied with corrosion rate and corrosion type.

Key words: LY12CZ LC4CS Electrochemical Noise simulated atmosphere contamination ion
