    Abstract

    An extensive testing program was carried out for studying the corrosion of steel and zinc in environments intended to model atmospheres containing SO2, SO42, sodium chloride (NaCl), and seawater. Both gaseous and droplet types of the corrosion stimulators were introduced into the system together, alternatively, or subsequently in graduated doses. The corrosion tests were performed in a cyclic mode. The weight losses, composition of corrosion products, and radiochemical detection of sulfates have been followed. Parallel stimulation of the steel and zinc atmospheric corrosion by the Cl and SO42 ions cannot be described by a simple relation. Further components of the reaction system participate in the control of the corrosion kinetics.
