“…37,38 As seen in Table 1, methanol and ethanol were widely used as solvents in the performed studies. However, other organic solvents, such as ethyl acetate, 39 acetone, 40 and methanol followed by butanol, 41 have also been employed. The extracts obtained were used to protect mostly pure aluminium and 1xxx series aluminium alloys in acidic solutions.…”

“…New and strict environmental rules strongly diverted the scholars' focus towards green chemicals (plant extract chemicals). A literature study cited that, many chemicals extracted from the plant species are less hurtful to nature and humans, which can act as an environmental benign inhibitor [25,[70][71][72][73][74][75][76][77][78]. Hence, in this review paper, reporting the application of green compounds as a corrosion inhibitors for aluminum in a hydrochloric acid solution.…”

Control of Al corrosion is of environmental, aesthetic, economical and technical importance. Ecologically acceptable, environment friendly and readily available corrosion inhibitors are the best option for the protection of Al against corrosion. In recent years, natural products (plant extract species) show the authentic promise towards inhibition of Al corrosion with zero environmental impact. Hence, herein, we have tried a review on of corrosion inhibition property of plant products on Al in HCl medium. The present article deliberately restricts mainly to the plant extracts as non-toxic corrosion inhibitors. The present review summarizes the published research work on the use of plant extracts as green corrosion inhibitors for Al in the HCl solution. Herein, the sample preparation, extraction and techniques employed to examine the inhibition effect of plant species and respective mechanisms of inhibition are discussed. Further, in the present article, missing gap, direction of research and future considerations were also proposed.

“…Five of the most common corrosion control practices are material selection, coating, inhibitor, cathodic protection, and design [4]. Although each means has its pros and cons, current research has long shifted towards the development of an excellent counter-measure by utilizing the beneficial property of different parts of plants [5][6][7][8][9][10][11]. The shift of interest occurred when the previous corrosion reducing agents are found to possess harmful effects on both the environment and human health [12].…”

Corrosion inhibition analysis of Leucaena leucocephala leaves extract (LLE) as an additive incorporated into a commercialized coating to protect mild steel when immersed in seawater has been successfully conducted. The procedures involve the utilization of multiple techniques including Fourier transform infrared spectroscopy (FTIR), ultravioletvisible spectroscopy (UV-Vis), electrochemical impedance spectroscopy (EIS), potentiodynamic polarization and scanning electron microscope with energy-dispersive Xray spectroscopy (SEM/EDS). The result of FTIR identified both hydroxyl (-OH) and carbonyl (C=O) groups indicating the presence of phenolic compounds in the extract whereas the analysis obtained from UV-Vis showed a peak absorption spectrum at 268 nm. The electrochemical analysis indicated an excellent inhibition efficiency up to 96.12% for the immersed mild steel coated with 6% of LLE coating. Furthermore, based on the study of polarization, a drastic decrease of corrosion rate at 0.2791 mm/year was observed for the same coating as compared to the uncoated substrate, which was 2.3991 mm/year. The study also confirmed that LLE acts as a mixed type inhibitor, as shown in the polarization curve. The morphological evaluation displayed a smooth and homogenous surface with less salt precipitation for 6% of LLE coating as compared to other types of coating affirming it to be the optimum concentration for this evaluation study.
