“…Thus, the charge transfer process could have taken place at the metal/electrolyte interface. 36 It is also observed from the Bode plots that a linear relationship between log| Z | vs. log( f ) was shown in the intermittent frequency region, indicating that the phase angle is less than −90° and the slope value is close to −1. These results justified the equivalent circuit obtained.…”

“…Usually, the impedance modulus | Z | at low frequencies was used to reflect the corrosion resistance capacitance of the coating (Xing et al , 2018; Chen et al , 2021; Liu et al , 2018; Du et al , 2021). The higher impedance modulus | Z | of the coating reflects the enhanced corrosion protection.…”

Purpose The purpose of this paper is to prepare a dual-encapsulated halloysite nano-container to release the capsuled inhibitor as an additive for corrosion protection of epoxy coating. Design/methodology/approach Halloysite nano-containers (HNT) were prepared by simultaneously implanting inhibitor benzotriazole (BTA) into the inside and outside of the halloysite using reduced pressure and layer-by-layer (LBL) assembly, respectively. The microstructure and morphology of treated HNT were investigated using Fourier transform infrared spectroscopy and transmission electron microscopy. In addition, the anti-corrosion behaviors of the composite polyepoxy coating with inhibitor-loaded nano-containers BTA@HNT-2 were investigated using the electrochemical impedance spectroscopy and neutral salt spray test. Findings Test results showed that the LBL assembly structure of the halloysite nano-container makes the BTA@HNT-2 nano-container be controlled and sustained to release BTA, relying on the pH. Very importantly, the obtained nano-container is also responsive to temperature, owing to the thermosensitivity polyelectrolyte out-shell of the HNT. The result showed Rct of the composite polyepoxy coating can be sufficient to maintain higher than 8.510E+7 Ω·cm2 over 72 h of immersion test. Moreover, the artificial induced defects on the coating surface were sufficiently inhibited in the presence of BTA@HNT-2 nano-container in the polyepoxy coating. Originality/value Use of the BTA@HNT-2 as corrosion inhibitor nano-container, with good anti-corrosion property and dual-responsive to pH and temperature, offers a significant rout to prepare smart anti-corrosion coating for protecting metal substrate.

“…metastable pitting) [43]. The RP-EDP plot can be divided into three types according to previous studies [44][45][46]: (1) Region A between D 1 and D 3 in the high frequency domain represents a reasonably fast phenomenon, such as metastable pitting and nucleation process, (2) Region B between D 3 and D 6 corresponds to the pitting development or nucleus growth process, and (3) Region C between D 6 and D 8 at a relatively lower frequency range mainly characterizes a slow process, such as adsorption or diffusion process.…”

A superhydrophobic surface featuring high roughness and low surface energy is designed for effective corrosion protection on aluminum via a facile and cost-effective electrochemical route. The effects of the electrolyte composition and electrodeposition time on the surface wettability were investigated. Moreover, the corrosion resistance performance of the as-prepared superhydrophobic aluminum surface was studied using electrochemical impedance spectroscopy and electrochemical noise techniques. The results show that the superhydrophobic aluminum surface obtained at 2 V for 20 min has a high static water contact angle of 155.8°. Both the average corrosion rate and pitting intensity are remarkably inhibited by the as-prepared superhydrophobic surface on aluminum. Moreover, the static water contact angle for the obtained superhydrophobic surface remains above 150°after exposure to 3.5 wt% NaCl solution for 30 days. This facile and economical superhydrophobic surface, with its excellent anti-corrosion property and stability, shows significant potential for use in industrial applications.
