Dibenzylidenecyclohexanone as a New Corrosion Inhibitor of Carbon Steel in 1 M HCl

Insight into corrosion inhibition mechanism of carbon steel by an algal extract as an eco‐friendly corrosion inhibitor in 0.5 M H2SO4: Experimental and molecular dynamics study

“…On the other hand, if the E corr shift <±85 mV, the inhibitor is of mixed electrochemical type. [31,32] In our study, the maximum displacement of E corr was −24.5 mV. These findings suggest that our inhibitor has mixed electrochemical behavior, as it acts by decreasing the anodic dissolution rate of the steel and reducing H + proton.…”

1-Butyl-3-methylimidazolium methane sulfonate ionic liquid corrosion inhibitor for mild steel alloy: Experimental, optimization and theoretical studies

“…7 c–d both HOMO and LUMO orbital distributions show significant divergence in the entire molecules. These outcomes demonstrate that [C 4 MIM][OMs] molecules have mobile locations by virtue of which they can interact with the mild steel surface [ 75 ]. Also, the HOMO orbitals are frequently connected with the capability to donate electrons from inhibitor molecules to a relevant acceptor [ 76 ] which is accredited to the high value of E HOMO (- 4.0640) energies compared to E LUMO (−1.0085).…”

Inhibition Mechanism of Some Vinylalkylimidazolium-Based Polymeric Ionic Liquids against Acid Corrosion of API 5L X60 Steel: Electrochemical and Surface Studies

“…The negative values of Δ G ° ads indicate that the adsorption of the CIs was thermodynamically spontaneous and suggest that a physicochemical adsorption process started through electrostatic forces between the steel surface and N heteroatoms present in the PILs such as vinylpyrrolidone, acrylamide, vinyl alkylimidazolium [VIM + ] cations, imidazolate [Im – ] anions, and bromides [Br – ]. In addition, chemisorption-coordinated complexes can be formed between the present IL species like vinylalkylimidazolium bromide or vinylbutyl imidazolium imidazolate and the vacant Fe d orbital on the metal surface.…”
