Study on anti-corrosion performance and mechanism of epoxy coatings based on basalt flake loaded aniline trimer

Enhanced Anti‐Corrosion Performance of Carbon Steels via CeO2@BNNSs/Epoxy Resin Composite Coatings

“…Previous studies have shown that better corrosion‐resistant coatings have larger Nyquist impedance arcs. [ 53 ] As seen in Figure 5a,b,c,d, the impedance arcs of all coatings decreased with the increase of corrosion levels along with the prolonging of immersion time, indicating that the corrosion resistance of the coatings decreased gradually. After 2 days of corrosion, the impedance arc of the pure EP coating is significantly reduced, because the corrosion medium penetrates the substrate surface through micropores, reducing the protective performance of the coating.…”

Comparison of inhibition performance of thiadiazole derivatives containing sulfhydryl groups: Experimental and theoretical calculations

“…The chemisorption of corrosion inhibitor molecules on the metal surface was usually the coordination action which was that the lone pair electrons of inhibitor molecules filled the insufficient valence electron orbitals of iron atoms 33 . The coordination activity was evaluated by Fukui index f ( r ), which was defined as the partial differential of electron density at points in space with respect to the number of electrons 34 $$$$\begin{equation}f \left( r \right) = {\left( {\frac{{\partial \mu }}{{\partial \nu \left( {\vec{r}} \right)}}} \right)}_N = {\left( {\frac{{\partial \rho \left( r \right)}}{{\partial N}}} \right)}_{\nu \left( {\vec{r}} \right)}\end{equation}$$$$…”

Preparation of Silicone Coating and Its Anti-Ice and Anti-Corrosion Properties

“…Metal corrosion can be categorized into chemical corrosion and electrochemical corrosion, with appropriate protection methods based on the underlying mechanism [13]. The mechanisms of corrosion protection can be broadly categorized into three types based on the mechanism of metal corrosion [14].…”
