Effect of silane on corrosion resistance and aerodynamic performance of 6063 Al alloy inertial air-water separator

Lei Wan et al.

Summary: The purpose of this study is to enhance the corrosion resistance of anodized 6063 Al alloy inertial air-water separator using silane technology and investigate the impact of corrosion-generated surface roughness changes on aerodynamic performance. The BTSE-KH560 double-layer silane film is used to seal microporous defects and reduce surface roughness. It is found that the silane film improves the corrosion resistance of the anodized film and the roughness caused by corrosion deteriorates the separator performance.

Benzothiazole derivatives-based supramolecular assemblies as efficient corrosion inhibitors for copper in artificial seawater: Formation, interfacial release and protective mechanisms

Zining Liu et al.

Summary: Host-guest assemblies of beta-cyclodextrin (beta-CD) loaded with 2-mercaptobenzothiazole (MBT) or 2-aminobenzothiazole (ABT) were used to distinguish their anticorrosive mechanisms for copper in aqueous phase. The protective efficacies were evaluated and MBT and ABT showed optimal inhibition efficiencies of 95.6% and 89.2% respectively using cathodic-dominated mixed-type inhibition mechanism at a dosage of 0.5 g/L. The differentiated inhibition behaviors were attributed to varied guest release mechanisms and different bonding strengths of Cu-S and Cu-N, as supported by theoretical simulations.

Ambient-stable polyethyleneimine functionalized Ti3C2TX nanohybrid corrosion inhibitor for copper in alkaline electrolyte

Yuxin Liu et al.

Summary: In this study, it was found that decorating polyethyleneimine (PEI) on Ti3C2TX could solve its oxidation problem in aqueous solutions. The functionalized Ti3C2TX with PEI exhibited excellent corrosion inhibition for copper in 0.5 M NaOH solution. The Ti-N bond formed by Coulomb attraction was responsible for the grafting of PEI. The anchored polymer chain effectively capped the oxidation-sensitive defects on Ti3C2TX, leading to improved colloidal stability. When the mass ratio of PEI/Ti3C2TX reached 0.33 (M@0.33P), the aqueous dispersion showed robust shelf-life for 30 days at 25 degrees C. M@nP acted as a mixed-type inhibitor with dominant anodic effect for copper in NaOH solutions, and M@0.33P was the optimal prototype that further mitigated copper dissolution. The protective mechanism of M@nP for copper in alkaline electrolyte involved reduction of interfacial cupric/cuprous species by Ti3C2TX, electrostatic adsorption, and electrons sharing of PEI.

Electronic effects on protective mechanism of electropolymerized coatings based on N-substituted aniline derivatives for mild steel in saline solution

Hao Liu et al.

Summary: Polyaniline, poly(N-methylaniline), and poly(N-formylanilide) coatings were prepared on mild steel using chronoamperometric strategy in an oxalate electrolyte. The coatings were evaluated for their anticorrosive effects, and it was found that poly(N-formylanilide) exhibited the highest protection capacity among the three coatings. Electroactivity and physical barrier were identified as critical factors for long-term corrosion protection.

Study on vapor phase corrosion inhibitor for E36 ship steel in marine atmospheric environment

Jie Ren et al.

Summary: This study investigated the effect of vapor phase corrosion inhibitors (VCI) such as imidazoline, quinoline, and urea on E36 ship steel in simulated marine atmospheric environment. The findings showed that the corrosion process was inhibited through the adsorption of these VCIs on the surface of the steel.

Modification and corrosion resistance of halloysite carrier with metal nanoinhibitor in marine corrosion environment

Yan Wang et al.

Summary: This paper studies the smart anti-corrosion coating of halloysite nanocontainers loaded with BTA inhibitors on copper in a marine corrosion environment. The surface topography and composition of the halloysite carrier were observed, and the physical and chemical properties of the inhibitors, as well as the mass change in halloysite, were evaluated. The results show that calcination at high temperatures enhances the efficiency of the nanotubes. The pH selectivity for the self-releasing of BTA out of the nanocontainers was also examined using electrochemical impedance spectroscopy.

Age hardening and intergranular corrosion behavior of new type Al-4.5Mg-0.6Zn-0.5Cu-XAg(wt%) alloy

Haitao Zhang et al.

Summary: The influence of T6 heat treatment process and Cu and Ag alloy elements on the microstructure, mechanical properties, and intergranular corrosion (IGC) performance of Al-Mg-Zn-Cu-Ag alloy was systematically studied. The addition of Ag element in the alloy led to the precipitation of nanoscale dispersive phases and an improvement in the mechanical properties. The alloy exhibited different IGC resistance depending on the aging states, with the solid solution state showing the best resistance.

Electrodeposition of silane/reduced graphene oxide nanocomposite on AA2024-T3 alloy with enhanced corrosion protection, chemical and mechanical stability

H. H. Zhang et al.

Summary: Hydrophobic silane/reduced graphene oxide (rGO) nanocomposites were successfully constructed on an AA2024-T3 aluminum alloy surface using a facile co-electrodeposition process. The composition and morphology of the nanocomposites were characterized, revealing a more compact and denser coating with excellent corrosion resistance and mechanical robustness. The results demonstrate the great potential of these nanocomposites for industrial applications.

Hong-Liang Zhang et al.

Summary: The complex films of benzotriazole and octadecylamine prepared on the surface of aluminum alloy via vapor phase self-assembly method showed better protection effect compared to single component films. The performance of the complex films is related to the sequence of vapor phase self-assembly, affecting the formation mechanism of the different complex films.

Review of micro-scale and atomic-scale corrosion mechanisms of second phases in aluminum alloys

Yuan-yuan Ji et al.

Summary: Localized corrosion of aluminum alloys, such as pitting corrosion, intergranular corrosion, and stress corrosion cracking, is closely related to micro-galvanic corrosion between the second phase and the Al matrix. Factors affecting the corrosion mechanisms of the second phase in Al alloys at micro and atomic scales were examined using high-resolution transmission electron microscopy and first principles calculations, including the composition and structure of the second phase, pH of the environment, stress, and adsorption behavior of adsorbates (such as CF, H2O, OH, and O-2).
