Abstract
The corrosion inhibition of the synthesis poly o-anisidine on 304 SS has been studied by using a different electrochemical technique such as potential-time measurement, EIS and polarization methods in 0.5 M HCl, and 3.5% NaCl solutions. The poly o-anisidine layer has been obtained on SS electrochemically from 0.5M H2SO4 acid solution by using cyclic voltammetric (CV), potentiostatic and galvanostatic techniques. The polymer layer provides around 93% protection in acid solution by potentiostatic coating. Nevertheless, the poly o-anisidine coating is not protected in 3.5% NaCl media by cyclic voltametry and galvanostatic coating. The examination of polymer surface by SEM confirms the results obtained. For characterization of polymer layer the UV-vis spectra and Fourier transform infrared (FTIR) spectra of the polymer films were measured. This work was aimed to study the effect of electrodeposition method of poly o-anisidine on corrosion protection of 304 SS.
