“…These peaks get shifted after the immersion of mild steel samples. The shift in the absorbance value indicates the adsorption of CI inhibitor molecules from the solution on the metal surface [44]. Based on this fact, it may be inferred that the phytochemical components are present in the CI leaf extract have been adsorbed on the surface of mild steel and prevents corrosion.…”

The anticorrosive activity of Combretum indicum (CI) leaf extract has been examined on mild steel corrosion in 1M HCl by using weight loss and electrochemical measurement techniques. The results of these experimental techniques have consistent in confirming the effect of the CI leaf extract on corrosion inhibition and a mechanism for the inhibition was proposed. The dissolution rate of steel in acidic solution was found to be sensitive to the concentration of CI leaf extract and the corrosion rate reduces when the concentration of CI leaf extract is increased and reaches the high protection efficiency. The potentiodynamic polarization study confirms the mixed mode of inhibition. Ultraviolet-visible (UV) and Fourier-transform infrared (FTIR) spectroscopic techniques were performed to evaluate the phenomenon of adsorption in the plant extract and the functional groups. The surface morphology analysis (SEM) further corroborates the adsorption of inhibitor molecules over the metal surface.

“…However, steel oxidize and corrosion easily occur due to corrosion in metal‐forming process, which owing to the aggressive chloride ions in aqueous and emulsion 2,3 . By addressing this problem, a lot of measures have been taken to improve the anticorrosion properties of mild steel, and the addition of corrosion inhibitors is one of the best ways to inhibit corrosion 4–6 . Therefore, all kinds of chemicals containing several heteroatoms (i.e., N, S, and O) have already been used as the inhibitors to hinder the corrosion of mild steel in the past several decades 7,8 .…”

Two imidazole derivatives, 2‐(2‐((benzo[d]thiazol‐2‐ylthio)methyl)‐4,5‐dihydro‐1H‐imidazol‐1‐yl)ethan‐1‐ol (BTM) and 2‐(2‐((1H‐benzo[d][1,2,3]triazol‐1‐yl)methyl)‐4,5‐dihydro‐1H‐imidazol‐1‐yl)ethan‐1‐ol (BTMS), as a new corrosion inhibitor were synthesized, and their inhibition behaviors for mild steel contained in emulsion were investigated by gravimetric experiment, electrochemical tests, and theoretical calculations. The results show that the inhibition effect of BTMS is better than that of BTM, the maximum value of the inhibition efficiency reaches 97.9%. The resultant adsorption films from BTM/BTMS adsorbed on mild steel, effectively inhibiting the corrosion of mild steel is mainly through chemisorption and follow to Langmuir's adsorption isotherm.

“…Corrosion inhibitors are mainly imperative in connection with the alkali cleaning or picking treatment as they applied to the surface of Al. Corrosion inhibitors are the customary chemical substance which, when added to the corrosive atmosphere dramatically blocks the cathodic and anodic reactions [1][2][3][4]. Alkali solutions of 40-60% sodium hydroxide (NaOH) by volume (containing ∼1% inhibitor) are employed at ambient temperature for the removal of dust and rust.…”

The present study focussed on the performance of a sapota leaf extract in controlling the aluminium (Al) corrosion in 3 M sodium hydroxide (NaOH) medium thoroughly investigated through gasometric, atomic absorption spectroscopy, electrochemical Tafel diagrams and impedance spectroscopy techniques. The outcome shows that small amounts of the sapota leaf extract are sufficient for the effective mitigation of the Al corrosion process in 3 M NaOH solution. The gasometric data revealed that four different concentrations of the plant extract inhibit the Al corrosion process and the protection efficiency of the inhibitor varies with time of the system. Type of inhibition was studied by an electrochemical potentiodynamic polarization technique. The alternating current impedance spectroscopy results show that the plant extract inhibits the corrosion process by forming a defensive layer on the Al surface through an adsorption process, which confirms the inhibition properties of the plant extract. The presence of electron rich groups in the sapota leaf extract was confirmed by the Fourier transform infrared and energy-dispersive X-ray spectroscopy techniques. The particle size of the sapota leaf extract can be analysed by an X-ray diffraction technique. Further, atomic force microscopy and contact angle results evidence the adsorption of the sapota leaf extract on the Al surface. The morphology of the Al surface in protected and unprotected systems was examined through scanning electron microscopy techniques.
