Abstract

Time–evolution study of 2-(2-pyridyl) benzimidazole (2PB) as CO₂ corrosion inhibitor for API X60 steel under hydrodynamic conditions in a synthetic brine solution has been undertaken. Electrochemical impedance spectroscopy (EIS) and potentiodynamic polarization (PDP) techniques were employed for this study. The results indicate that 2.56 mM of 2PB could provide up to 88.3 % inhibition efficiency after 12 h at 4000 rpm in the synthetic brine solution. The addition of 0.14 mM thiobarbituric acid (TBA) significantly enhances 2PB performance to 95.6 % using PDP. ATR-IR, SEM and optical image characterizations confirm that 2PB adsorption suppresses the localized corrosion of the steel.
