Estimating the synergistic corrosion inhibition potency of (2-(3,4-)-3,5,7-trihydroxy-4H-chromen-4-one) and trivalent-cerium ions on mild steel in NaCl solution

Amino-Functionalized MXene Nanosheets Doped with Ce(III) as Potent Nanocontainers toward Self-Healing Epoxy Nanocomposite Coating for Corrosion Protection of Mild Steel

“…However, the release of Ce 3+ from Ti 3 C 2 MXene-Ce 3+ nanosheets enhanced the CPP of the epoxy coating. However, as reported in the literature, 56,63 Ce 3+ can increase the hydrophilicity of the metallic surface after adsorption. That is why a descending trend was observed for |Z| 0.01 Hz and R t values of the MXene-Ce 3+ @EP coating as a function of time.…”

“…58 For mild steel samples immersed in the blank solution, lower n dl values is an indication of the surface deterioration and the formation of porous rusts and corrosion products on mild steel plates in the absence of Ce 3+ corrosion inhibitor. Higher values of both n f and n dl for mild steel samples immersed in the 56 Moreover, values of Y 0,dl , which show the ionic charge distribution at the metal/electrolyte interface for mild steel samples, reduced in the order of the blank > Ti 3 C 2 MXene extract > Ti 3 C 2 MXene-Ce 3+ extract. Also, some fluctuations were observed in Y 0,dl values, which can be related to the adsorption/desorption of ions and formation/dissolution of corrosion products at the metal/electrolyte interface.…”

“…These unsoluble components can be deposited on cathodic zones and form inhibitive layers on the surface of mild steel plates. 55,56 As stated in the literature, cerium-based inhibitors in saline solutions can not provide a prolonged inhibition. 56,57 That is why, for the Ti 3 C 2 MXene-Ce 3+ extract, higher values of |Z| 0.01 Hz and R t were observed after 12 h of immersion.…”

“…As presented in Figure 15 and Table 7, in the solution phase, different types of cerium hydroxides/oxides such as Ce(OH) 3 , Ce(OH) 4 , and CeO 2 and iron oxides/hydroxides such as Fe 3 O 4 , Fe 2 O 3 , Fe(OH) 3 , and FeOOH, which are insoluble in aqueous solutions can be formed. 56,64 Consequently, the deposition of these components on the cathodic and anodic sites constructs an inhibitive layer on the metallic surface.…”
