Eriobotrya japonica Lindl leaves extract application for effective corrosion mitigation of mild steel in HCl solution: Experimental and computational studies

Corrosion mitigation of mild steel in hydrochloric acid solution using grape seed extract

“…Furthermore, as shown in Fig. 9 , an increase in GSE concentration resulted in the establishment of a smoother surface with fewer cracks, indicating less corrosion damage and improved surface film integrity 25 , 40 . The SEM–EDS results are consistent with the electrochemical test results, in which an increase in the GSE concentration resulted in a reduction in the reaction area, a phenomenon known as the blanketing effect of corrosion inhibitors on the metal surface 41 .…”

Experimental and DFT studies on the ultrasonic energy-assisted extraction of the phytochemicals of Catharanthus roseus as green corrosion inhibitors for mild steel in NaCl medium

“…In the case of mild steel immersed in the phytochemicals of stem, the surface is corrugated possibly because the phytochemicals are agglomerated on the steel surface however there is no evidence of surface attack, or pits. 40,41 The microstructure of mild steel immersed in the phytochemicals of root extract demonstrates a smooth surface with some evidence of crevices due to the initiation of localized corrosion on the mild steel surface. Earlier results reported that the extracts of medicinal plants have signicant corrosion retardation in an acidic medium due to the fused ring and active groups of phytochemicals.…”

Inhibition of Carbon Steel Corrosion by Some New Organic 2-Hydroselenoacetamide Derivatives in HCl Medium

“…The action of inhibitors can be explained by the molecular adsorption of inhibitors on the surface of the alloy. The effective adsorption is a result of the interact of π-electrons of multiple bonds and aromatic system of inhibitor molecules with the metal, or interaction of lone pair electron present on highly electronegative atoms (N and O) in the structure of inhibitors molecules with dorbital of iron [21][22][23]33].…”
