Investigation of 6-[5-(4-Methoxyphenyl) furan-2-yl] Nicotinonitrile as a New Corrosion Inhibitor for Carbon Steel in Acidic Solution: Chemical, Electrochemical and Quantum Chemical Studies

Evaluation of Curam drug as an ecofriendly corrosion inhibitor for protection of stainless steel‐304 in hydrochloric acid solution: Chemical, electrochemical, and surface morphology studies

“…But, in case of the presence of Curam drug the surface of the inhibited SS‐304 specimen becomes smoothened as seen in (Figure 6c) The average roughness of SS‐304 samples before and after immersion in 2.0 M HCl solution without and with inhibitor were found as 28, 382, 117 nm, respectively. The lower value of the roughness in the presence of the Curam drug (Figure 6c) was compared to the roughness observed after immersion of the sample in the corrosive medium without inhibitor, which leads to that the Curam drug is reduced the corrosion rate and is more resistant to damage of the SS‐304 surface 38 . This is clearly due to the formation of a protective layer adsorbed on the SS‐304 surface.…”

“…This is due to, the adsorption of Curam inhibitor molecules on the metal surface, which leads to the formation of a protective layer on the metal surface, which reduces the corrosion reaction and increases the inhibition efficiency. On the other hand, it is clear that, with rising the temperature, the desorption of inhibitor molecules from the metal surface increased, which reduces %IE and increases the CR 26 …”

“…spectra for Curam drug (red color), and SS-304 surface covered with investigated drug (blue color) Comparison of Curam drug performance with some expired drugs as corrosion inhibitors is more resistant to damage of the SS-304 surface 38. This is clearly due to the formation of a protective layer adsorbed on the SS-304 surface.…”

Investigation of Anticorrosive Property of Carbazolecarbaldehyde Azine on Mild Steel Using Electrochemical, Morphological and Theoretical Studies

“…It can be observed that the characteristic azine band for CH=N-N=CH at 1614 cm −1 and that for C-N stretch at 1232 cm −1 in CCA was displaced to 1662 cm −1 and 1254 cm −1 , respectively, in the corrosion product. These shifts in the IR frequencies of the functional groups present in CCA before and after adsorption to MS might be due to the metal-inhibitor interactions through functional groups [46].…”
