Abstract
Various tools were used in the investigation and analysis processes of the iron window grille of sabil Ramadan. Metallographic Microscope, SEM-EDS Microscope, Carbon-Sulfur, and XRD analysis indicated that the iron window grille was manufactured from low carbon steel. X-ray diffraction of corrosion products showed that they mainly consist of Magnetite Fe3O4, Goethite α-FeO(OH), and Akaganeite β-FeO(OH). Such information regarding the iron window may assist in the conservation process of this iron window. Coatings and inhibitors are used in a wide range in this field, where Special methods are required either for protection or treatment to stop or reduce corrosion rate. Experiments were performed on coupons simulating iron window to evaluate the efficiency of polyamide by using electrochemical techniques (electrochemical impedance spectroscopy (EIS) and polarization resistance (RP)). It gave sufficient protection and good results of the electrochemical measurements. Tannic acid diluted in 5% methyl alcohol (coating) and polyamide (inhibitor) applied to protect the iron window grille.
