Outdoor and indoor atmospheric corrosion of carbon steel

The atmospheric corrosion of carbon steel under different Cuban atmospheric conditions was evaluated. Pollutants (mainly chloride ions and SO2) and me teorological parameters were also determined. A classification of the corro sivity of atmospheric test stations based on these data was made according to ISO 9223. The difference among the corrosion rate values obtained for ea ch exposure condition, as well as for each type of atmosphere, was noticeab le. A model that represents the relation between the corrosion of carbon st eel and the environmental parameters is proposed. The proposed model fits v ery well with the experimental data. The corrosion products formed were ana lysed by infrared spectroscopy. (C) 1998 Elsevier Science Ltd. All rights r eserved.
