“…Electrochemical impedance spectroscopy (EIS) was completed in the frequency range of 0.1 Hz to 100 kHz with a sine amplitude of 10 mV at E ocp . Corrosion current density (j cor ) was determined by the extrapolation of anodic and cathodic Tafel lines to corrosion potential (E cor ) [6].…”

“…Corrosion inhibitors are one of the experimental approaches used for protection against corrosion, specifically in acidic solutions [4][5][6][7][8]. The various inhibitors that have been applied and test industrially as corrosion additives [9][10][11][12] are those are low-or nontoxic are currently better than the materials used in the recent past such as glucose, gellan gum, carboxymethyl, hydroxypropyl cellulose [9,11], xanthan gum [10], and chitosan-g-PEG [12].…”

In this work, a Zn–benzenetricarboxylic acid (Zn@H3BTC) organic framework coated with a dispersed layer of chitosan (CH/Zn@H3BTC) was synthesized using a solvothermal approach. The synthesized CH/Zn@H3BTC was characterized by Fourier transform infrared spectroscopy (FTIR), field emission scanning electron microscope (FESEM), thermal gravimetric analysis (TGA), and Brunauer, Emmett, and Teller (BET) surface area. The microscopic observation and the analysis of the BET surface area of CH/Zn@H3BTC nanocomposites indicated that chitosan plays an important role in controlling the surface morphology and surface properties of the Zn@H3BTC. The obtained findings showed that the surface area and particle size diameter were in the range of 80 m2 g−1 and 800 nm, respectively. The corrosion protection characteristics of the CH/Zn@H3BTC composite in comparison to pristine chitosan on duplex steel in 2.0 M H2SO4 medium determined by electrochemical (E vs. time, PDP, and EIS) approaches exhibited that the entire charge transfer resistance of the chitosan- and CH/Zn@H3BTC-composite-protected films on the duplex steel substrate was comparatively large, at 252.4 and 364.8 Ω cm2 with protection capacities of 94.1% and 97.8%, respectively, in comparison to the unprotected metal surface (Rp = 20.6 Ω cm2), indicating the films efficiently protected the metal from corrosion. After dipping the uninhabited and protected systems, the surface topographies of the duplex steel were inspected by FESEM. We found the adsorption of the CH/Zn@H3BTC composite on the metal interface obeys the model of the Langmuir isotherm. The CH/Zn@H3BTC composite revealed outstanding adsorption on the metal interface as established by MD simulations and DFT calculations. Consequently, we found that the designed CH/Zn@H3BTC composite shows potential as an applicant inhibitor for steel protection.

“…For complex mortar, hydration products at the metal-hydrated cement paste interface may affect the onset of localized corrosion, complicating the analysis of the The formation velocity and the long-term stability of the protective film are among the most important indicators to evaluate the efficiency of inhibitors. However, organic substances can disintegrate the form of the steel bar surface due to the desorption effect, leading to a lack of long-term stability [16,17]. On the other hand, the inorganic inhibitors become non-effective in high alkaline conditions because the formation velocity of inorganic inhibitors on steel bars is lower than the corrosion reaction introduced by chloride.…”

Comparative Studies on Steel Corrosion Resistance of Different Inhibitors in Chloride Environment: The Effects of Multi-Functional Protective Film

A corrosion inhibitor was widely used to improve corrosion resistance of steel bar in reinforcement concrete structure. A kind of multi-component corrosion inhibitor, which is composed of organic and inorganic substances, was developed in this research. This corrosion inhibitor was comparatively studied with various other inhibitors by using open circuit potential (OCP), electrochemical impedance spectroscopy (EIS), and cyclic voltammetry (CV) methods. The results show that the OCP values and charge transfer resistance (calculated by EIS curves) of the multi-component corrosion inhibitor remain, respectively, as high as −0.45 V and 932.19 kΩ·cm−2 after 60 days immersion, which are significantly better than other groups. Wide passivation interval and various peaks in cyclic voltammograms (CV) were applied to analyze the mechanism of adsorption (organic substance) and oxidation–reduction reactions (inorganic substance). The functional groups -OH in triethanolamine (TEA) and tri-isopropanolamine (TIPA) bond to the steel bar surface quickly, behaving as an adsorbent of organic substance in early age. An additional protective precipitate related to the reactions of Fe3+ was formed by inorganic substances (Fe2(MoO4)3 and FePO4), which is consistent with the EIS results and equivalent electrochemical circuits. As an eco-friendly substitute, multi-component corrosion inhibitors possess similar or even better protecting effects on steel bars in comparison to calcium nitrite. In addition, the concept of a “multi-functional protective film” was proposed, providing a new insight to achieve modified anti-corrosion capacity of inhibitors.

The most common way to control Top of line Corrosion (TLC) is to use corrosion inhibitors. A setup was designed to simulate the TLC conditions and measure the corrosion rate in the presence of an Imidazoline-based commercial inhibitor. The base solution was at temperature 70°C and the samples X65 steel were at 5°C and 20°C. Experiments were carried out in atmospheric conditions by purging a mixture of CO 2 and H 2 S gases in proportions of 21% and 79%, respectively. An increase in the TLC rate was measured when the sample temperature increased. The difference between the average corrosion rate measured by weight loss and the instantaneous resulting from Tafel and linear polarisation resistance was significant in this study. Results showed that the surface temperature of the sample has a significant effect on TLC. Although the condensation rate on X65 steel sample with surface temperature of 5°C was about ten times more at 20°C, the corrosion rate was more at higher temperatures.
