Within a cooperative program for the elaboration of a Latin American Map of Atmospheric Corrosion, weathering steel and mild steel samples were exposed to the Antarctic atmosphere and the corrosion products analyzed by ICEMS, XPS and XRD. Superparamagnetic α-FeOOH was the main corrosion product after 24 h of exposure. Cl− ions are found on the surface of the corroded samples by XPS.
