Inhibition Effect of Triphenylmethane Dyes for the Corrosion of Carbon Steel in CO2-Saturated NaCl Corrosion Medium

“…Weight loss measurement is simple and straightforward to use to evaluate the corrosion of metals [ 25 ]. Table 1 lists the results of specimens exposed to the solution with 100 ppm inhibitors for three days at 40 °C.…”

“…A higher diameter of the capacitive arc reflects the formation of potential barriers that must be resolved to facilitate charge transfer, suggesting a decrease in the rate of corrosion [ 28 ]. Moreover, the wide phase angle peaks in the presence of CV indicate the existence of two time constants compared to the blank solution in the Bode plots, indicating that the corrosion inhibitor has successfully adsorbed on the surface of the steel sheet to form a corresponding adsorption film [ 25 ]. The equivalent circuit moles are used to fit the EIS data without or with CV and are shown in Figure 2 .…”

“…Weight loss measurement is simple and straightforward to use to evaluate the corrosion of metals [25]. Table 1 lists the results of specimens exposed to the solution with 100 ppm inhibitors for three days at 40 • C. The corrosion rate and inhibition efficiency of the specimens in the solution with CV, MG, and FB are 0.050 mm/y, 0.102 mm/y, and 0.143 mm/y and 82.8%, 64.1%, and 49.8%, respectively, while the average corrosion rate is 0.323 mm/y in the blank solution.…”

“…The linear correlation coefficient (R 2 ) is 0.99, demonstrating that CV follows the Langmuir adsorption model. As calculated, the Gibbs free energy (∆G 0 abs ) of the corrosion inhibitor is −27.496 kJ/mol, indicating that the adsorption type of this adsorbent simultaneously exhibits physical adsorption and chemical adsorption [25]. Taking into consideration the impact of temperature on the corrosion inhibitor, the corrosion kinetics were further investigated in this process.…”

Corrosion Inhibition Mechanism of Water-Soluble Imidazoline on A572 Gr.65 Steel in 3.5 wt % NaCl Solution

“…Corrosion inhibitors play a pivotal role in safeguarding metals against the deleterious effects of corrosion. , The utilization of these substances in minute quantities exhibits an extraordinary capacity to substantially diminish the rate at which metal undergoes corrosion. They effectively minimize oxidation loss and have extensive usage in acidic, neutral, and alkaline environments. , In comparison to other corrosion protection methods (such as cathodic protection of sacrificial anode, alloying, and coating), the utilization of corrosion inhibitors offers advantages in terms of ease of operation, accessibility, and cost-effectiveness .…”
