“…[18,28,32,33]. The higher E * a can be correlated with the increased thickness of the formed double layer, which increases the activation energy of the corrosion process [4,16,23,34]. The E * a values in the presence of Itraconazole and Fluconazole are nearly similar, suggesting that the two inhibitors inhibit the corrosion process with similar mechanisms.…”

Corrosion inhibition and adsorption behavior of two triazole derivatives on API 5L-B carbon steel in CO 2 -saturated 3.5% NaCl solutions was investigated using potentiodynamic polarization, EIS, and EFM techniques. Specimen surfaces were characterized using SEM, EDX, and XRD. Results show that the two compounds are mixed-type inhibitors and inhibition efficiency increases with increasing concentrations. Adsorption of the two compounds chemisorption and obeys Langmuir adsorption isotherm. Activation energy and thermodynamic parameters were calculated. Surface analyses confirm the formation of iron nitrides on the metal surface which supports results obtained from previous techniques.

“…[19,28,32,33] The higher E Ã a can be correlated with the increased thickness of the formed double layer, which increases the activation energy of the corrosion process. [4,17,24,34] The E Ã a values in the presence of itraconazole and fluconazole are nearly similar, suggesting that the two inhibitors inhibit the corrosion process with similar mechanisms. It is also indicated that the whole corrosion process is controlled by surface reaction, since the activation energy (E Ã a ) of the corrosion process is over (20 kJ mol À1 ).…”

GRAPHICAL ABSTRACTCorrosion inhibition and adsorption behavior of two triazole derivatives on API 5L-B carbon steel in CO 2 -saturated 3.5% NaCl solutions was investigated using potentiodynamic polarization, EIS and EFM techniques. Specimen surfaces were characterized using SEM, EDX and XRD. Results show that the two compounds are mixed-type inhibitors and inhibition efficiency increases with increasing concentrations. Adsorption of the two compounds is a mixed between chemisorptions and physisorption and obeys Langmuir adsorption isotherm. Activation energy and thermodynamic parameters were calculated. Surface analyses confirm the formation of iron nitrides on the metal surface, which supports results obtained from previous techniques.

“…The values of cathodic Tafel slope (b c ) and anodic Tafel slope (b a ) of the inhibitors are found to change with inhibitor concentration, indicating that the inhibitor controlled both the reactions. In other words, the inhibitors decrease the surface area for corrosion without affecting the mechanism of corrosion and only cause inactivation of a part of the surface with respect to the corrosive medium [25]. Complete data obtained from polarization measurements are summarized and listed in Table 4.…”

The inhibitive effects of newly synthesized non-ionic surfactant based on alkylene diamine surfactants on X-65 carbon steel in formation water was investigated by means of electrochemical techniques and quantum chemical study. These derivatives were characterized by FT-IR, and the surface tension and thermodynamic parameters were calculated. The polarization showed that the inhibition efficiency of the prepared compounds was increased with increasing the length of the internal alkyl chain between the two terminal amino groups of diamine. The electronic properties obtained using quantum chemical approach were correlated with the experimental inhibition efficiencies. The surface morphology of carbon steel was investigated using SEM.
