dc.description.abstractA novel, relatively inexpensive ionic liquid, 1.3-bis[2-(4-methoxyphenyl)-2-oxoethyl]-1H–benzimidazol-3-ium bromide (MOBB), was synthesized and characterized using FTIR, NMR, LC-MS and single crystal XRD (SCXRD) techniques. MOBB was evaluated for its corrosion inhibition properties on 6061 Al-15 vol% SiC <inf>(P)</inf> composite in 0.1 M HCl and 0.1 M H<inf>2</inf>SO<inf>4</inf> media at different temperatures (30–50 °C) by electrochemical impedance spectroscopy and potentiodynamic polarization methods. The adsorption of MOBB on the composite was predominantly through chemisorption, obeying Langmuir adsorption isotherm. Inhibition efficiencies of 98.7% in HCl and 98.8% in H<inf>2</inf>SO<inf>4</inf> were obtained, MOBB acting as a mixed type of inhibitor with predominant cathodic control. © 2016
