ABSTRACT:
The effect of addition of Vitamin B-2 on the corrosion of steel in 0.5M H2SO4 acid has been studied by weight loss measurements, potentiodynamic polarisation and Electrochemical Impedance Spectroscopy (EIS) measurements. The inhibition efficiency was found to increase with inhibitors content to attain 59.38% and 91.66% Vitamin B-2 and 25ppm TBAB respectively. Data obtained from EIS studies were analyzed to determinate the model inhibition process through appropriate equivalent circuit models. Inhibition efficiency E (%) obtained from the various methods is in good agreement.
