Description:
<jats:p> </jats:p>
<jats:p>The atmospheric corrosion, potentially destructive consuming sources and time, is the electrochemical process in which metals are deteriorate by atmospheric factors, that include the effect of climate conditions (periods of wetting and drying, temperature, humidity, rainfall, wind speed and direction, solar and ultraviolet radiation) and the effect of pollution (SO<jats:sub>2</jats:sub>, NaCl, CO<jats:sub>2</jats:sub>, NOx and solid particles). Another factor is that atmospheric corrosion involves chemical, electrochemical and physical process in three mater states (solid, liquid and gaseous) and two interfaces (solid/liquid and liquid/atmosphere). </jats:p>
<jats:p>In the present study painted galvanized steel sheets were exposed to different environments which include marine, industrial and urban conditions. The aim was study the corrosion behavior of the materials in the different climatic environments. To characterize the corrosion behavior a photographic register was done and an analysis of the layers in cross section with a scanning electron microscope. </jats:p>
