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. M3 ER -
