Corrosion in rural atmospheres in Spain

Abstract

There is little quantitative information available regarding the effect of atmospheric variables on metallic corrosion in pure (unpolluted) atmospheres. This paper reports on research to investigate the effect of time of wetness, relative humidity, rainfall, and temperature on the corrosion of mild steel, zinc, copper, and aluminium exposed at a large number of rural sites in Spain. Empirical equations are established for the atmospheric corrosion of these four metals, based on the multiple linear regression technique.
