- Abstract
- In this study, the optimum amount of hybrid inhibitors i.e. L-Arginine (LA) and sodium phosphate tribasic dodecahydrate
(SP), applied for carbon steel rebar in simulated pore concrete (SCP) solution contaminated with 3.5 wt.% NaCl, was
discovered. The corrosion inhibition performance of hybrid inhibitors was investigated by open circuit potential (OCP),
electrochemical impedance spectroscopy (EIS), and potentiodynamic polarization. The highest corrosion inhibition efficiency
was found as 99.52% corresponding to 2% LA and 0.25% SP after 210 h exposure. Anodic type inhibition action was
confirmed by potentiodynamic polarization study. Surface studies including scanning electron microscopy (SEM), and atomic
force microscopy (AFM) were used to figure out the surface morphology of the steel rebar treated with hybrid inhibitors in
order to collaborate with electrochemical studies.
