Abstract
The aim of this work is to report the results of a study on plain stee l exposed for four weeks to acidic fogs. These included two levels of NO3-, both alone and in combination with SO42-, at 35 degrees C and 90 % RH. Gravimetric analysis, XRD, FTIR and polarized light microscopica l examinations were used to follow the corrosion effects and the rust trasformations. As a major conclusion, it was found that atmospheric N Ox deposited by fogs had no important effect.
