Abstract

The inhibition effect of Tetra-n-butylammonium bromide (TBAB) on the corrosion of mild steel in Sulphuric acid was investigated. The corrosion inhibiting action was studied through weight loss, polarization and electrochemical impedance spectroscopy techniques. The surface characterization was done by scanning electron microscopy. The polarization experiment reveals that the studied inhibitor acts as mixed type inhibitor. The %IE increases with increase in concentration but decreases with increase in temperature .Langmuir adsorption isotherm fits the experimental data for the studied compound. Thermodynamic and kinetic parameters are evaluated.SEM study provide the confirmatory evidence for the protection of mild steel by the studied inhibitor.
