Atmospheric Aerosols Corrosion

Atmospheric pollutant is one of the important factors influencing the atmospheric corro- sion; pollutants mainly exist in the form of aerosols and affect the atmospheric corrosion of metals through aerosols deposition. In this paper, the factors which would influence the atmospheric corro- sion of metals such as size and distribution, chemistry, transmission and deposition of aerosols were introduced. The physical, chemical and electrochemical interaction between aerosol and metal surface, and constituent of pollutants in aerosol were reviewed emphatically in order to summarize the influence of aerosols on metal corrosion and the mechanism of atmospheric aerosols corrosion. Present situation of studies on aerosols corrosion at home and abroad was discussed. Finally, the prospect of studies on aerosols corrosion was also predicted.
