Abstract

Copper alloy samples are subjected to climate chamber test to simulate corrosion compounds of copper artifacts in atmospheric environment. Relative humidity and air pollution considered as an essential source of deterioration and corrosion of archaeological objects. Corroded copper coupons were investigated by X-ray diffraction analysis (XRD) and scanning electron microscopy with energy dispersive X-ray analysis (SEM-EDX) to identify elemental composition of coupon samples and the corrosion products. Mechanical cleaning was used in order to clean the copper coupon surface and carried out nanocomposite coating on treated copper surface. To evaluate performance of titanium dioxide TiO₂ / Paraloid B.72 nanocomposite, the nanocomposite coating applied as a thin film at different times (10, 15, 30 minutes). The electrochemical impedance spectroscopy (EIS) of nanocomposite coating layers on treated copper coupons showed different results; that the best layer was obtained from the coupon which immersed in nanocomposite coating for 15min. To prove successes of TiO₂ / Paraloid B.72 nanocomposite as a good protection coating applied on treated copper objects. Nanocomposite coating of TiO₂ / Paraloid B.72 were examined under X-ray diffraction analysis (XRD), Raman Spectroscopy, Atomic Force Microscopy (AFM), and Contact angle, which revealed control the wettability and TiO₂ / Paraloid B.72 nanocomposite is completely covers and protects the copper substrate without any degradation.
