“…On the Bode format, the spectra reveal two-phase maxima in the θ-log f plot, while the log f − log |Z | plot exhibits no observable resistive behavior in the LF region, though it was measured down to a lower f value of 10 mHz. Thus, instead of a horizontal plateau with zero slopes appeared at the LF range the plot deflects upward, implying that the corrosion reaction of carbon steel in the produced water is under diffusion control [17,18]. This trait is also corroborated by the low value of the phase maximum (θ max ), being of ~45°, indicating that a Warburg impedance (W) should be involved in the LF time constant [17] of the adopted equivalent circuit (EC) simulating the corrosion process.…”

The present study evaluates the effect of Camellia sinensis leaves (CSL) extract on the corrosion inhibition of carbon steel in produced water using potentiodynamic polarization, electrochemical impedance spectroscopy (EIS) and computational methods. The chromatographic investigation of the extract was performed by HPLC. It was found that CSL extract serves as a mixed-type corrosion inhibitor and its inhibitive performance increases with concentration. The corrosion inhibition was assumed to occur via adsorption of the primary constituents of CSL extract. Surface analysis (SEM and FTIR) was also carried out to establish the mechanism of corrosion inhibition. The outcomes obtained from the computational study were found to confirm experimental data.

“…For a rough or porous surface, non-homogeneity can cause the double layer capacitance to appear as a constant phase element. 31 This model consists of two-time constants ((Q 1 R 1 W) and (Q 2 R 2 )) parallel to each other and all in series to the solution resistance (R s ). The rst time constant (Q 1 R 1 W) expresses the behavior at LF region and is attributed to the adsorbed lm while the other one (Q 2 R 2 ) is related to the HF region and describes the behavior of the double layer at the base of pores or defects in the lm.…”

“…Surface enhancement conrms the inhibitive and protective action of these gemini surfactants for C-steel in oileld water. 31 The corresponding EDX spectra show that there is a reduction in the amount of corrosion products where the peaks corresponding to salts and oxides formed due to corrosion process are diminished. The reduction in the amount of corrosion products conrms the anti-corrosion effect of these gemini surfactants for C-steel in oileld water.…”

Synthesis and assessment of new cationic gemini surfactants as inhibitors for carbon steel corrosion in oilfield water

et al. 2017

Three gemini surfactants were synthesized having the same length of terminal chain but differing in the spacer chain length and they were evaluated as corrosion inhibitors for carbon steel in oilfield water using weight loss, EIS, potentiodynamic polarization and open-circuit potential measurements. These measurements revealed that the synthesized materials have served as effective mixed-type corrosion inhibitors. Their adsorption on a carbon steel surface was well described by means of the Langmuir adsorption isotherm. The activation parameters for the dissolution of carbon steel in solutions of oilfield water in the absence and presence of these inhibitors were calculated. The effect of immersion time on the stability and durability of protective films adsorbed on a carbon steel surface was studied using weight loss method. Ex situ inspection, i.e. post-exposure analysis, for the treated carbon steel surface has been performed using SEM, EDX and FT-IR tools.

“…Most of these inhibitors are unfortunately toxic and not friendly to the environment. Thus, several studies have been conducted to examine essential oils and organic compounds extracted from natural resources [6][7][8][9][10][11][12][13][14][15][16].…”

Brass is widely used as turbine material for cooling system for marine propellers. However, it is vulnerable to corrosion by contact of air or aqueous chloride solution. The essential oil of Myrtus communis (MO) was tested as a brass corrosion inhibitor (Cu70-Zn30) immersed in the 3% NaCl solution, using a polarization technique and electrochemical impedance spectroscopy. The effect of MO concentration, temperature and immersion time was studied to evaluate the action of the inhibitor. The results showed that the protection efficiency was enhanced with the increasing of MO concentration, and the potentiodynamic polarization experiment showed that MO acts essentially as a cathodic inhibitor. In addition, experiments have shown that MO inhibition efficiency decreases with increasing immersion time and temperature. The film adsorbed on the brass surface containing MO was confirmed by the results of the Scanning Electron Microscope (SEM) and the Energy Dispersive X-ray (EDX). The overall results affirmed the potential use of MO as inhibitor agent of brass corrosion in the 3% NaCl solution.
