Polyamide Coating as a Potential Protective Layer Against Corrosion of Iron Artifacts

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