Article Description

Inhibition ability of green tea extract (GTE) on the C38 steel (CS) in 1.0 M HCl was evaluated using different methods such as: weight loss, electrochemical impedance spectroscopy ( EIS ) and potentiodynamic polarization ( PDP ) methods at various temperatures. Polarisation curves show that GTE acts essentially as mixed-type inhibitor controlling cathodic and anodic reactions with slight predominant in cathodic branches. EIS results indicate the increase of resistance transfer ( R t ) while double layer capacitance (C dl ) decrease in the rise of green tea extract (GTE) concentrations. Obtained results also showed that the inhibition efficiency decreased with a rise in the temperature. Activation energy ( E a ), enthalpy (Δ H a ⁎ ) and entropy and (Δ S a ⁎ ) of corrosion process were estimated using experimental measurements.
