Octylsilanol and Ce(III) ions – alternative corrosion inhibitors for carbon steel in chloride neutral solutions

Investigation of Dracocephalum extract based on bulk and nanometer size as green corrosion inhibitor for mild steel in different corrosive media

“…The experiment is carried out using a modest potential of 10 mV of AC voltage and frequencies ranging from 100 kHz to 100 mHz. The inhibition efficiency ( IE I ) of a corrosion inhibitor was estimated using the following equation utilizing electrochemical data collected from the workstation 42 : where R ct , and R′ ct are the polarization resistance of the sample in the presence, and absence of the corrosion inhibitor, respectively.…”

Ce-loaded silica nanoparticles in the epoxy nanocomposite coating for anticorrosion protection of carbon steel

“…Without nanoparticles, during 18 days of immersion, the neat epoxy coated steel has its OCP values oscillating from −330 mV to −480 mV/SCE, whereas with the presence of SiO 2 @Ce nanoparticles, the OCP values of epoxy nanocomposite coating varies from −210 mV to −330 mV/SCE. The anodic shift of OCP values indicate the action of Ce 3+ as the cathodic inhibitor (Cotting and Aoki, 2020).…”

Analysis of inhibitory properties of Ce‐citrate as a green corrosion inhibitor of low alloy steel in neutral chloride solution

“…Among carboxylates, cinnamates (3-phenyl propionate and their different derivatives) have shown the best results as good ligands for rare earth cations. [19][20][21][22][23][24][25] Other combinations of organic ligands such as salicylates, [18,26] acetylacetonate, [27] anthranilates, [28] octylsilanol, [29] and methyl-benzoyl-propanoate [30] with rare earth metals, primarily cerium cations, have been investigated. Recently, carboxylate inhibitors with different alkyl chain lengths as corrosion inhibitors of carbon steel have been tested.…”
