Abstract
It is proved that inhibitors control or reduce the onset time of corrosion of steel rebars. The nitrite based i.e. sodium or calcium nitrite corrosion inhibitor is very popular and significantly reduces the corrosion of steel rebars. In this study, the effect of LiNO2 was evaluated by electrochemical impedance spectroscopy (EIS) and potentiodynamic studies. This inhibitor showed 63.67% efficiency at [Cl-/NO2-] = 0.6 in Ca(OH)2 solution contaminated with 0.99 g/L NaCl. LiNO2 works as mixed type corrosion inhibitor by stabilizing the iron oxides/hydroxides in their stable form and stifle the corrosion of steel rebar.
