Atmospheric corrosion in the metal pool of Ali Qapu palace in Isfahan: an experimental study

Abstract Isfahan, the capital of Iran during Safavid period (1501–1736 CE), houses Ali Qapu Palace. It was constructed to be used as royal court and a place for settling affairs country. The palace built in five stages; final stage porch which contains pool at its centre. perimeter is made white marble, floor walls are covered with metal sheets marble attached. Today, dry exposed urban environment metropolis Isfahan. This study investigates composition corrosion mechanism using optical microscopy, ICP-OES, SEM–EDS X-ray diffraction techniques. results show that pool’s cover large number copper joined together by lead nails. forging (cold-working annealing) method form sheets. products formed on surface oxide trihydroxychlorides. pool, including oxidation, due formation (II) compounds resulting from reaction Cl-contaminated airborne particulate matters (dust).
