摘要：
In this study, atmospheric corrosion of copper exposed for 4 years in 12 different cities of Iran with various climatic characteristics was determined by weight loss method. Also, the corrosivity index of each city was classified using environmental factors according to the ISO 9223 standard. The results indicated good agreement between two approaches recommended by ISO standards. Accordingly, the corrosion rate of copper in Iran can be predicted according to the empirical kinetic equation . Morphology, chemical composition and crystalline phases of patinas in cities with different kinetic behaviours were compared via SEM, EDS and XRD, respectively.
