Long-term atmospheric corrosion in Spain: results after 13-16 years of exposure and comparison with worldwide data

This paper reports the results obtained after 13-16 yrs of field exposure tests at various Spanish test sites including several types of atmosphere: rural, urban, industrial and marine. Panels of low-carbon steel, zinc, copper, and aluminum were removed from open-air racks after different years of exposure, and their weight losses used to determine the corrosion rate. Long-term corrosion data were found to conform to a general equation, C = Atn, where A and C are the corrosion losses after one and t years of exposure, respectively, and n is a constant. Results were compared with those found throughout the world, which were compiled in a comprehensive literature survey.Peer Reviewe
