Argentinean map of atmospheric corrosivities
In the present paper the results obtained by the Argentinean research groups integrated in the MICAT (Iberoamerican Map of Atmospheric Corrosion) Project are given. Outdoor exposure in 6 test situations of different environmental conditions were performed by quadruplicate, on plain carbon steel and pure zinc, copper and aluminium, during yearly periods from 1 to 4 years. Three samples were used for the weight loss determinations while the fourth one was used to characterize the corrosion products formed through electrochemical d.c. and a.c. techniques and SEM-EDAX surface analysis. Good correlations were observed among the corrosion rates, the environmental conditions, both electrochemical techniques and the morphology of the rusts in plant and in polished cross sections. The techniques applied allowed to evidence the different protectiveness of the rusts formed on the metals, according to the solubility, morphology, hygroscopic power and pollutants content of the corrosion products` components.
