“…The study in Table 4 showed that β a values are approximately constant in the presence of different C. siliqua extracts while β c values change, this shows that anodic and cathodic reactions are carried out but that the effect on cathodic reactions is greater. These results are completely in accord with the work carried out on the extract of Artemesia herba albamedium used as corrosion inhibitor of stainless steel in solution 1 M H 3 PO 4 [83]. It is also noted from the results that the inhibitory efficacy E(%) increases with the increase in the concentration of C. siliqua extracts.…”

The effect of C. siliqua pulp corrosion inhibition on carbon steel has been studied by gravimetric testing and electrochemical methods. In this study, two raw extracts were prepared from the pod pulp of C. siliqua: the first is methanolic and the second is aqueous. The UHPLC/DAD analysis indicated gallic acid's presence in the extracts (methanolic and aqueous) of C. siliqua as a major compound. The inhibition results achieved revealed that the aqueous extract with gallic acid had a good anticorrosion activity with an inhibition rate of 91.32% at 3 g/l for a temperature of 323 K. Potentiodynamic polarization was performed in 1 M HCl without and with different concentrations of C. siliqua extracts clearly proves that inhibitor extracts behave as mixed type. Adsorption of this inhibitor for different extracts studied on the surface of the carbon steel obeys Langmuir adsorption with negative values of ΔG • ads , suggesting a stable and spontaneous inhibition process.

“…Inhibition efficiency increases with temperature and oil concentration to reach 74% at 1 g/L. Boudiala et al [57], worked on the essential oil they extracted from the aerial parts of Artemisia herba-alba from Morocco. This essential oil was tested as a corrosion inhibitor of stainless steel (SS) in HCL acid (1 M) using potentiodynamic polarization (PDP) measurements, electrochemical impedance spectroscopy (EIS) and scanning electron microscopy studies (SEM).…”

Natural and aromatic substances contained in plants which can be extracted by hydro-distillation or by cold extraction, more commonly known as essential oils are used today in several fields including cosmetic, perfumery, food processing, traditional medicine, agriculture etc. More recently, a strong use of these products extracted from plants as a corrosion inhibitor of metals and alloys in an acidic environment has been observed, given the number of works that have been published in recent decades. This review represents a general study on essential oils for a better understanding of these natural products, but also a non-exhaustive study of the published research works on the use of essential oils as a corrosion inhibitor of metals and alloys, in particular mild steels in acidic environments. Most of these studies have revealed great potentials of essential oils in inhibiting the corrosion of metals in aggressive environment, such as acidic environment. Thus, they have proposed alternatives to artificial metal corrosion inhibitor known to cause environmental pollution and public health issues. This review is a contribution to research efforts carried out by scientific community to find green corrosion inhibitors. It lays the basis for future research work aimed to investigate on the corrosion inhibition properties of essential oils extracted from Senegalese local plants.

“…As shown in table 3, the increase of the polarization resistance R p values and the decrease of the capacitance values of the double-layer C dl with the increase of the inhibitor concentration are explained by the absorption of inhibiting molecules on the metal surface while replacing the water molecules present in the electrolyte. The deviation of the N dl value from the ideal capacitive behaviour of the CPE indicates non-uniformity and surface roughness [2,34,35]. The increase of the film resistance R f indicates the thickening of the adsorbed organic layer on the surface, which in turn allows the reduction to the number of active sites, thereby increasing the inhibition efficiency (ɳ %).…”

“…High mechanical strength and low cost are important characteristics that ensure widespread use of metallic materials in the marine environment, particularly in production, processing, transportation and construction of underground pipelines, fuel tanks and heat exchangers [1][2][3][4][5]. Nevertheless, the high content of aggressive sodium chloride in marine water contributes to a decrease in the corrosion resistance, strength and workability of many metals and alloys.…”

Synthesis and evaluation of corrosion inhibitory and adsorptive properties of N-(β-ethoxypropionitrile-N,N-bis(2-hydroxyethylethoxy) fatty amide

The present study reports a synthetic condensation process of a vegetable oil (waste) reacted with triethanolamine, maleic anhydride and acrylonitrile in (1 : 1.2 : 2 : 1) mole ratios to obtain N-(β-ethoxypropionitrile)-N,N-bis(2-hydroxyethylethoxy) fatty amide as a major inhibitory product. Corrosion property of steel in a 3% NaCl solution in the presence of a potential inhibitor was investigated using weight loss, potentiodynamic polarization and electrochemical impedance spectroscopy (EIS) methods. These methods gave consistent results, from which it is noticeable that inhibition efficiency increases with the increasing concentration of the inhibitor. Gravimetric studies show an increase in the sample mass at an inhibitor concentration of 10 mM, indicative of adsorbed film formation on the surface. The polarization curve results showed that the compound demonstrates itself as an anodic-type inhibitor. A rise in polarization resistance values in the EIS measurements also confirmed that the compound acts as an effective inhibitor of steel corrosion. Furthermore, the R(CR)(QR) equivalent circuit was used to interpret the results obtained in the investigation of the corrosion behaviour of steel in solution with an inhibitor. The standard adsorption free energies calculated from the Langmuir isotherm indicate that adsorption takes place by physical and chemical mechanisms. The presence of adsorbed protective film was confirmed by FT-IR spectrum and SEM micrographs.
