Corrosion protection of mild steel in 0.5 M H2SO4 solution
was studied using combination of benzene-1,2-diamine and benzaldehyde with FeCl3 to in situ
synthesis of new inhibitor at different temperatures employing electrochemical, weight loss,
quantum chemical studies and optical microscopy. The electrochemical results represent the
combination of these components in the solution shows equal efficiency to the compound which was
synthesized in the laboratory which is 2-phenyl-1H-benzo[d]imidazole. To indicate this compound
was created on the metal surface, deposited layer was investigated by Fourier transform infrared
spectroscopy (FTIR). Optical microscopy examinations demonstrate a decrease in corrosion attacks
in presence of inhibitors. (C) 2013 Elsevier Ltd. All rights reserved.
