“…As shown in Figure 7, the two-dimensional (2D) surface morphology of mild steel treated with 1 M HCl reveals a severe crack in the surface (Figure 7a) and 1 M HCl with 600 ppm inhibitor significantly diminished the surface crack (Figure 7b) [61][62][63]. The average roughness (251 nm) of the mild steel before the exposure to acidic solution were noticed and, in the presence of the optimal concentration of C. tagal plant extract, the reduced average roughness was determined (65 nm), which confirmed the anticorrosion efficiency of the adsorbed inhibitor molecules produced by the protective film [64][65][66].…”

“…It is evident that C. tagal extract is competent with other known green inhibitors, as it exhibits the strongest inhibition against mild steel corrosion in 1 M HCl. As in Table 5, plant extracts such as Aster koraiensis (90.53%) [23], Cryptostegia grandiflora (87.54%) [25], sweet melon peel (91.59%) [30], Desmodium triflorum (92.99%), Polycarpaea corymbose (91.78%) [32], Citrullus lanatus (91%) [57], Lawsonia inermis (92.06%) [62], Lepidagathis keralensis (92.73%) [63], Mangifera indica (92%) [64], Mentha pulegium (80%) [65], and Petroselium Sativum (92.39%) [66] were overcome by the acceptable results of C. tagal extract.…”

Mangroves are plants known for their various medicinal and economical values, and therefore are widely investigated for their phytochemical, antioxidant, antidiarrheal, and antimicrobial activities. In the present study, we analyze the antioxidant and anticorrosive properties of Ceriops tagal (C. tagal), a tropical and subtropical mangrove plant of the Rhizophoraceae family. The total phenolic content (TPC) and total flavonoid content (TFC) were found to be 101.52 and 35.71 mg/g, respectively. The extract (100 µg/mL) exhibited 83.88, 85, and 87% antioxidant property against 1,1-diphenyl-2-picrylhydrazyl (DPPH), nitric oxide, and hydrogen peroxide free radicals. In addition, 600 ppm of C. tagal extract showed 95% corrosion inhibition against 1 M HCl attack on mild steel at 303 ± 1 K, which declined over other concentrations and temperatures, where AAS produced 82% inhibition at 600 ppm. UV-visible spectroscopy analysis revealed the formation of an inhibitor metal complex. The elemental analysis provided the presence of 84.21, 9.01, and 6.37% of Fe, O, and C, respectively, in inhibited mild steel, whereas the same were 71.54, 22.1, and 4.34%, respectively, in uninhibited specimen, stressing the presence of protective film on the metal surface. Scanning electron microscopy (SEM) also showed some noteworthy changes in both uninhibited and inhibited mild steel, making C. tagal plant a better alternative than any other synthetic inhibitors. Further, the atomic force microscopy (AFM) surface topography analysis showed that 600 ppm of C. tagal extract significantly diminished corrosion on the surface of mild steel.

“…After being treated with green tea and Tulsi leaf extracts, the impedance property of the al alloys changed significantly. Higher impedance was measured at the highest inhibitor concentration because the bioactive components of the leaf extract were more readily adsorbed onto the Al alloy electrode [ 53 ]. As can be observed in the plot, the impedance of inhibitors derived from Tulsi extract is significantly greater than that of extracts derived from green tea leaves or of no inhibitors at all.…”

In this work, a cerium/tetraethylenepentamine dithiocarbamate complex was synthesized and evaluated for the corrosion inhibition capability on an AA2024-T3 Al alloy in a 3.5% NaCl medium. The synthesized compounds were characterized via spectroscopic techniques. The corrosion inhibition behaviour of the complex was elucidated by electrochemical measurements and surface analysis techniques. Based on electrochemical test results, the corrosion inhibition efficiency of the complex increases with the immersion time of aluminium alloy in the test solution. The corrosion inhibition reaches 96.80% when the aluminium is immersed in a 3.5% NaCl solution containing a corrosion inhibitor for 120 h. The potentiodynamic polarization test results show that the complex acts as a mixed-type corrosion inhibitor and the passive range is widened. The surface analysis methods reveal that the corrosion inhibition ability of the complex originated from the formation of a protective layer on the Al surface. This film is created from the physisorption and chemisorption of cerium ions and organic parts simultaneously released from the complex molecules.
