Abstract

CEMS was used in conjunction with AES to study the protective film formed on a weathering steel by exposure to a highly SO2-polluted atmosphere. Ferrous species (sulphite) and ferric oxyhydroxides (ferrihydrite and α-FeOOH) were identified as corrosion products. From the correlation of CEMS and AES results the evolution with time of the different compounds is obtained, and a possible reaction sequence is outlined.
