During the excavations of Tappeh Ghalaychi near the
city of Bukan in west Azerbaijan province, a number of iron and
bronze objects were found that are belonged to the 8th century
B.C. The corrosion of iron objects were studied after chemical
analysis. As these objects have a very high cultural value,
chemical analysis by using destructive methods is not possible,
therefore scanning electron microscope with energy dispersive
X-ray microanalysis (SEM·EDX), which allows analysis without
any damaging the Objects, was used. Likewise for analyzing the
corrosion area of the metal objects, Fourier transform infrared
(Ff-IR) spectroscopy and X-ray diffraction (XRD) were also
used. The results of this research showed that a layer of
magnetite which is covered with a layer of hematite exists at the
surface of the iron Objects. In addition, wuestite and goethite
were identified in the corrosion products layers.
