Abstract The atmospheric environment was simulated by using environmental scanning electron microscope and the formation process of the water film on the LY12 Al surfaces contaminated by dust,oil and NaCl was observed.The investigation showed that the water film is easier to form on the contaminated samples than on clean samples,which results in atmospheric corrosion.

Key words: Environmental Scanning Electron Microscope Aluminium Atmospheric Corrosion Water film
