Onion Peel Extract/Copper Oxide Nanoparticles as Corrosion Inhibitors for Carbon Steel in Hydrochloric Acid: Extraction, Characterization, Electrochemical Study, and Theoretical Explorations

The effectiveness of onion peel extract (OPE) as a corrosion inhibitor for carbon steel in a 1 M hydrochloric acid solution was investigated using weight loss (WL) techniques, potentiodynamic polarization (PDP), electrochemical impedance spectroscopy (EIS), and surface morphological examination. Additionally, this process was characterized by Fourier transform infrared (FT-IR) spectroscopy, energy dispersive X-ray spectroscopy (EDX), thermogravimetric analysis (TGA), atomic force microscopy (AFM), and transmission electron microscopy (TEM). According to weight loss measurements, the protective efficiency of OPE increases with rising OPE concentration and decreases with increasing temperature of the corrosive solution. Polarization curves indicate that OPE acts as a mixed-type inhibitor in hydrochloric acid. The adsorption mechanism, supported by EIS results, shows that charge-transfer resistance increases and double-layer capacitance decreases with higher inhibitor concentration. The adherence of OPE to carbon steel follows the Langmuir isotherm, indicating a physical adsorption process, and the spontaneous adsorption of the inhibitor molecules is evidenced by the negative values of Gibb’s free energy of adsorption. The synergistic effect of copper oxide nanoparticles (CuO–NPs) in combination with OPE on the corrosion inhibition of carbon steel was also evaluated. The results demonstrated that the inhibition efficiency of OPE is enhanced in the presence of CuO–NPs due to synergistic interactions between OPE extract molecules and CuO–NPs. The electron-donating capacity of the chemical components in OPE was confirmed through theoretical studies employing quantum chemistry methods.

Developing a novel imine derivative as a corrosion inhibitor for Q235 carbon steel in 1 M HCl solution: Experiments and theoretical calculations

During oil and gas extraction, metals are inevitably exposed to acidic environments on a regular basis. Acid solutions, particularly hydrochloric acid, are employed in a multitude of industrial processes, including oil well acidising, steel pickling, ferroalloy pickling and acid cleaning. These applications frequently result in severe metal corrosion. To cope with corrosion, the superlative simple and effective method is to prevent corrosion inhibitors. Naphthyridinimides are not as effective as rust inhibitors, but their corrosion inhibition is significantly improved by the addition of Br ions. This thesis focuses on the synthesis of naphthylimine-type novel organic corrosion inhibitors and the corrosion inhibition mechanism, with the main content of 3,3′-(1,3,6,8-tetraoxo-1,3 6,8-tetrahydrobenzo[lmn] [3,8] phenanthroline-2,7-diyl) bis (N-ethyl -N, N-Dimethyl-1-propylamine) bromide (NDI-N-Br) on Q235 carbon steel in an acidic environment (1 M hydrochloric acid solution). The corrosion inhibition efficiencies of NDI-N-Br reached 93.53 % at 300 ppm at an ambient temperature of 298 K. The corrosion inhibitor NDI-N-Br forms a protective film on the metal surface and organizes the interaction between the metal matrix and the corrosive medium, providing a rust inhibiting effect. This thesis shows that this class of compounds can be well applied to acidic environments and provide ideas for the subsequent development of naphthylimide-based organic corrosion inhibitors.

Evaluation of the Potential of Daucus crinitus Extracts and Their Synthesized ZnO Nanoparticles in Inhibiting the Corrosion of Carbon Steel

This study explores Daucus crinitus extracts (DCE) and zinc oxide nanoparticles (ZnO-NPs) synthesized using the extracts as corrosion inhibitors for carbon steel (CS) in HCl medium. The synthesized ZnO-NPs were characterized via UV-vis spectroscopy, exhibiting a peak at approximately 375 nm. The study employed weight loss (WL) and electrochemical measurements, alongside spectrophotometric evaluation of corrosion products. Surface morphology was assessed via scanning electron microscopy coupled with energy dispersive spectroscopy (SEM-EDS). Thermodynamic analysis revealed the physical adsorption of DCE on CS according to the Freundlich adsorption isotherm. Potentiodynamic polarization (PP) measurements indicated DCE as a mixed-type corrosion inhibitor. Electrochemical impedance spectroscopy (EIS) exhibited increased charge transfer resistance and reduced double-layer capacitance with inhibitory addition. The most effective inhibition was observed with butanol extract (BE) and improved more with its corresponding nanoparticles (BENPs), exhibiting inhibitory efficiencies of 80.20% and 91.20%, respectively, at 298 K with a concentration of 800 ppm. The evaluation of corrosion products using colorimetry revealed that the concentration of polyphenols decreased after the inhibitory process. Furthermore, the intensity of ferrous ions (Fe2+) decreased as the inhibitory concentration increased. In addition, SEM-EDS analysis confirmed the presence of ZnO-NPs, which enhanced the surface morphology and established a protective layer formed by the adsorbed inhibitors. The SEM-EDS analysis confirmed the presence of ZnO-NPs, the enhancement of surface morphology, and the establishment of a protective layer formed by the adsorbed inhibitors.

Effect of Oil-Water Intermittent Wetting on Corrosion Inhibition of Carbon Steel in CO2 Environment

ABSTRACT Produced water can cause internal corrosion in oil pipelines. The flow of hydrocarbons and water can result in intermittent surface wetting, which can impact corrosion inhibition. However, this is still poorly understood. This research studies the impact of intermittent wetting and the wettability of the steel surface on corrosion inhibition, utilizing electrochemical techniques. An inhibitor model compound and model oil were employed at 25°C and 55°C in CO2 saturated solutions. Corrosion inhibition varied with temperature and steel surface hydrophobicity, altering inhibition significantly after intermittent contact with hydrocarbon at 55°C. EIS and wettability results revealed distinct protective mechanisms when oil was present.

Humic acid as eco‐friendly corrosion inhibitor for EH40 ship plate steel

In this study, a new type of green corrosion inhibitor, namely, sodium humate (SH), was extracted from humus soil, which is a natural humus plant, by dissolution‐neutralization, and then used for corrosion inhibition of low carbon steel in seawater. The corrosion inhibition performance of SH on low carbon steel EH40 in seawater was tested by weight loss method and electrochemical technology. The surface and corrosion products of low carbon steel were observed and analyzed by scanning electron microscope (SEM), atomic force microscope (AFM), contact angle and X‐ray photoelectron spectroscopy (XPS). The results show that SH is a mixed corrosion inhibitor, and the optimum concentration is 2 g L−1. At this concentration, the inhibition rate can reach 93.6%. It mainly affects the semi‐reaction of cathodic corrosion. By forming a corrosion protection layer with uniform adsorption on the surface of EH40 steel, EH40 steel becomes more resistant to seawater corrosion.

Comparative study of morpholine-based ligands on corrosion inhibition of C-steel in 0.5 M H2SO4 solution: Chemical and electrochemical exploration

The inhibition of carbon-steel (C-steel) corrosion in 0.5 M H2SO4 media using three morpholine-based compounds, N1-(2-morpholinoethyl)-N1-([pyridine-2-yl]methyl)propane-1,3-diamine (H1), 2-((3-(2-morpholinoethylamino)-N3-((pyridine-2-yl)methyl) propylimino) methyl)pyridine (H2), and N1-(2-morpholinoethyl)-N1,N3-bis(pyridine-2-ylmethyl)propane-1,3-diamine (H3), at room temperature (RT) and higher temperatures, was investigated using electrochemical and chemical methods. The Tafel results showed that the highest corrosion current density (Icorr) is related to the sample without an inhibitor, with a value of 6.3 × 10−5 A.cm−2, and adding inhibitors reduced the values. The lowest Icorr is associated with the sample containing H3 with a concentration of 2.0 mM, which is 0.3 × 10−5 A.cm−2. According to the electrochemical impedance spectroscopy (EIS) results, with an increase in the concentrations of inhibitors H1, H2, and H3 from 0.2 to 2.0 mM, the value of charge transfer resistance (Rct) increases. In addition, Tafel and EIS results confirm that the inhibitor H3 shows better results in corrosion protection. The immersion results of C-steel in a 0.5 M H2SO4 solution without the inhibitor also showed that the highest corrosion rate occurs at 30 and 50 °C. At 30 °C, inhibitors H1, H2, and H3 offer stability for one, two, and three days, respectively. However, at 50 °C, inhibitors H1 and H2 decompose on the first day and do not provide good protective conditions, while sample H3 shows relatively good stability in a 0.5 M H2SO4 environment at 50 °C. In general, inhibitor H3 offers better corrosion protection performance at 30 and 50 °C compared with H1 and H2. According to the R2 values, the adsorption isotherm model of inhibitor H1 follows the Freundlich model, while inhibitors H2 and H3 follow the Langmuir model. The scanning electron microscopy (SEM) results also suggest that the surface of the C-steel sample after corrosion in the inhibitor-free solution has the highest corrosion and surface roughness. Adding inhibitors H1, H2, and H3 significantly reduces the corrosion, and sample H3 shows better surface conditions than the other samples.

Experimental and computational studies of novel cyclic ammonium based ionic liquids as corrosion inhibitors for carbon steel in acid medium

The challenge of corrosion posed as a result of acidic sittings is considered as a major industrial concern, wherein ionic liquids serve as crucial in addressing the corrosive impacts on metals. In this study, five selected cyclic ammonium based ionic liquids were synthesized; IL-1MPyrBr, IL-1MPipBr, IL-2PyBr, IL-3MPyBr and IL-4MPyBr and their chemical structures were characterized using a variety of spectroscopic techniques (FT-IR, IH-NMR, 13C-NMR, Elemental analysis and thermal gravimetric analysis (TGA). Their corrosion inhibition efficiency was studied on carbon steel in 1 M HCl via different concentrations at 298 K using chemical and electrochemical parameters (PDP and EIS). DFT quantum parameters were computed, and the noted results were in complete compatible with the experimental. The synthesized ILs recorded excellent inhibition on the carbon steel corrosion in acidic media with increasing efficiency by increasing the inhibitor concentrations from 20 to 100 ppm. Different cations in the synthesized ILs affect the anti-corrosion effect and IL-3MPyBr showed the highest inhibition (ηR); 96.12% using the lowest concentration. Kinetic and thermodynamic considerations were studied and illustrated.

Inhibition performance of a novel quinoxaline derivative for carbon steel corrosion in 1 M HCl

In this work, the effect of a new quinoxaline derivative, 2-phenyl-3-(prop-2-yn-1-yloxy) quinoxaline (PYQX), was evaluated as a corrosion inhibitor for carbon steel (CS) in 1 M HCl electrolyte. Weight loss measurement, atomic absorption spectroscopy, potentio­dynamic polarization, electrochemical impedance spectroscopy, scanning electron microscopy with energy dispersive spectroscopy, and UV-vis spectroscopy were employed to assess the inhibitory activity. The electronic properties of the interaction between the inhibitor molecule and the CS substrate were studied using molecular dynamics (MD) simulation, density functional theory (DFT), and Fukui functions. According to AC impedance experiments, the inhibitor under consideration showed a maximum level of 98.1 % inhibition efficiency at 1 mM and 30 °C. The Langmuir adsorption isotherm model explains the adsorption of PYQX on the CS surface. A slope of 1 denotes a strong molecule-substrate interaction, suggesting that the binding occurs at specific surface locations. To understand the functioning of the adsorption mechanism, various thermodynamic and activation parameters were evaluated. PDP tests demonstrated that PYQX functions as a mixed-type inhibitor. Computational correlations (DFT, MD, and Fukui indices) supported the experimental findings.

Synthesis and study of the inhibitory properties of a new Schiff base for C45 carbon steel in 1 M HCl

A newly Schiff base 1, 13-bis-[(4-dimethylamino) benzaldehyde 4, 7, 10-trioxatridecane-diimine] (DABT) was synthesized and characterized on the basis of the results of FT-IR, mass spectroscopy (MS), 1HNMR and 13CNMR. The desired performance of the organic compound DABT which is easy, inexpensive to prepare and eco-friendly, as a corrosion inhibitor for C45 carbon steel in 1 M HCl medium was evaluated using weight loss, potentiodynamic polarization, electrochemical impedance spectroscopy (EIS) measurements. The results suggest that the corrosion inhibition effectiveness increases with increasing inhibitor concentration and decreases with increasing temperature. The polarization experiments demonstrate that DABT exhibits the characteristics of a mixed-type inhibitor and follows the Langmuir isotherm in its adsorption behavior. Contact angle measurement revealed that the inhibitor on the surface of the carbon steel is hydrophobic. The synergistic effect of DABT has been investigated; inhibitory efficiency rises with increasing concentration of KI by competitive adsorption to form a layer of protection on the metal surface. Energy dispersive X-ray spectroscopy (EDS) combined with scanning electron microscope (SEM) was utilized to interpret the morphological study of the carbon steel surface. A good correlation was found between theoretical [Density functional theory (DFT), molecular dynamics simulation (MDS)] and experimental findings.

Study the Effect of “Di-dodecyl amine” as a Corrosion Inhibitor for Carbon Steel in HCl Medium

Numerous organic compounds have been investigated for their potential to reduce corrosion under various circumstances. This study investigated the effects of di-dodecyl amine, an organic chemical, on carbon steel metal corrosion at different temperatures while HCl acid was present. The examination was carried out using accepted methods for polarization, weight loss, and corrosion process testing. The obtained findings demonstrated that the corrosion rate reduces with increasing inhibitor concentration, leading to increased inhibition efficiency. Furthermore, as shown in the weight loss technique, the corrosion rate lowers with increasing surface coverage with organic inhibitor at 313 °C. In the anodic and cathodic polarization methods, as well as in the inhibition efficiency, it is observed to see the cathodic and anodic curves through which the occurrence of the potential and corrosion current is known. The current and corrosion potential decreases with increasing inhibitor concentration. The amines and methyl motiveless in this inhibitor's composition give it their efficacy since they may coat the metal surface and stop corrosion
