Inhibition effect of 1-ethyl-3-methylimidazolium dicyanamide against steel corrosion
Source abstract
Abstract
Abstract The inhibition efficiency of 1-ethyl-3-methylimidazolium dicyanamide (EMID) was studied against mild steel corrosion, in acidic environment. Surface analysis showed that the assembled inhibitor film could protect the metal successfully, during 120 h exposure to 0.1 M H 2 SO 4 . The studies considering zero charge potential value ( E pzc ) showed that the anion plays the major role for film formation. The surface coverage ratio ( θ ) values were determined handling the double layer capacitance values ( C dl ) calculated from Bode diagrams, for different concentration and temperature conditions. The inhibitor was fixed successfully within polypyrrole film and applied to steel surface as highly protective coating.
