Nickel-iron alloy is broadly utilized in the industrial field due to its fabulous mechanical properties. How to prepare nickel-iron alloy with better corrosion resistance more efficiently is an important concern. Based on this, the WC particles enhanced nickel-iron coatings were fabricated by jet electrodeposition (JED) at a high current density of 100A/dm 2 . It was found that increasing the deposition temperature appropriately during JED is beneficial to obtain Ni-Fe-WC coating with the higher number of hard particles. Specifically, the maximum WC particles proportion reaches 4.47 wt% at 55 °C. The electrochemical corrosion behavior of coating was measured by polarization curve and electrochemical impedance spectroscopy (EIS). The polarization curve test results displayed that the E corr positively shifted from −0.402 to −0.281 V and the i corr reduced from 25.13 to 7.05 μA/cm 2 with the increase of WC particles proportion. Meanwhile, the EIS test results exhibited that the impedance of coating enhanced from 12,720 to 59,140 Ω cm 2 . The neutral salt spray test (NSS) was used to simulate the corrosion of coating in a seawater environment. The NSS results showed that with the increase of WC particles, the corrosion products decreased gradually and the degree of corrosion decreased. The analysis showed that WC particles can help the grain growth and release the internal stress in the coating. Larger grain sizes reduces intergranular corrosion and smaller internal stress help to alleviate stress corrosion cracking. The above research can provide theoretical support for the efficient preparation of particle enhanced composite coating with strong corrosion resistance.

A novel CeO 2 /MgAl 2 O 4 composite coating, fabricated via a cathode plasma electrolytic deposition (CPED) technique followed by hydrothermal synthesis, was developed in this study to explore its potential application as corrosion protection for AZ31 magnesium alloys. The microstructure observed through scanning electron microscopy indicated that reducing the duty cycle of the power source within a reasonable range during the CPED process was beneficial to form a uniform and dense MgAl 2 O 4 coating, which served as an ideal adhesive matrix for a uniform CeO 2 coating as the outermost layer. The results of electrochemical impedance spectra and neutral salt spray tests showed that the decoration of the CeO 2 layer significantly improved the corrosion resistance of the CeO 2 /MgAl 2 O 4 composite coating compared to the single MgAl 2 O 4 coating and bare substrate. Cross-cut tests revealed that the adhesion of the MgAl 2 O 4 coating and the CeO 2 /MgAl 2 O 4 composite coating were both excellent due to the strong binding between the MgAl 2 O 4 coating and the substrate.

Corrosion is a major challenge across various industries, leading to significant economic losses and safety hazards. This study synthesized polypyrrole nanotubes (PPy-NTs) using methyl orange (MO) as a template and polyvinylpyrrolidone (PVP) as a dispersant. The PPy-NTs exhibited excellent dispersion stability (zeta potential of 34 mV) and high electrical conductivity (28.5 S/cm). Waterborne polyurethane (WPU)-based coatings with varying PPy-NT concentrations (0 %, 0.5 %, 1.0 %, and 2.0 %) were evaluated for corrosion resistance in a 3.5 wt% NaCl solution over immersion periods of 1, 7, 14, and 28 days. Electrochemical impedance spectroscopy (EIS) showed that the 1.0 % PPy-NT coating provided the best corrosion protection, with an initial impedance about 30 times higher than the pure WPU coating. After 28 days, its impedance remained over 200 times higher than that of the pure WPU coating. Polarization tests confirmed the 1.0 % PPy-NT coating had improved corrosion resistance, with a lower corrosion current density (49.4 nA/cm²) and higher corrosion potential (-0.13 V) compared to the pure WPU coating (636 nA/cm², −0.58 V). Salt spray testing showed the 1.0 % PPy-NT coating had superior corrosion resistance. These results demonstrate the enhancement of WPU coatings with PPy-NTs, showing potential for long-term corrosion protection.

Epoxy resins play a vital role in anticorrosion coatings, however, the defects of poor flexibility and thermal stability of epoxy resin hinder their use in extreme environments and limit the wide range of applications for epoxy coatings. This study investigates the incorporation of high-performance thermoplastic poly(phthalazinone ether) resins (PPAEs) into bisphenol A epoxy resins (E-51) to develop a series of high performance anti-corrosion coatings. Due to the distinctive structure of the phthalazinone moiety, the flexibility and thermal stability of the epoxy coatings were greatly improved by the addition of PPAEs. The flexibility test result was reduced from over 7.5 mm to 5 mm, while the glass transition temperature ( T g ) of the coating was stabilised above 180 °C. In addition, inorganic fillers are added to plug defects such as pores inherent in epoxy coating systems. The coating provided more than 1,560 h of protection in the neutral salt spray test. At the same time, the coating maintained a high impedance modulus of 10 9 Ω⋅cm 2 (|Z| 0.01Hz ) after 4 weeks of immersion in electrochemical impedance tests. This study significantly enhances the comprehensive performance of epoxy coatings and provides a viable solution for the development of high performance epoxy anti-corrosion coatings, offering promising alternatives for corrosion protection in extreme service environments.

Owing to the increasingly stringent environmental regulations, eco-friendly waterborne epoxy (WEP) coating currently gets much attention as an alternative choice of traditional coating. But the intrinsic problems of WEP, including poor barrier property and lack of long-term anticorrosion performance, was a limitation for its application. Herein, α-zirconium phosphate (α-ZrP) was prepared and exfoliated under mild condition. Then α-ZrP after exfoliation was functionalized by eco-friendly phytic acid (PA) molecular and a novel nano-filler (PZ) was obtained. The test results of the XRD , FTIR, SEM, TEM and XPS indicated that the preparation of nano-materials was successful. Through the EIS test, the outstanding barrier property of WEP incorporating with PZ was proved. Moreover, the excellent long-term anticorrosion performance of WEP incorporating with PZ was also proved by the salt spray test .

A novel sustained-release system was designed on the basis of metal–organic framework-5 (MOF-5) as a nanocontainer to load benzotriazole (BTA). Furthermore, the fabricated BTA/MOF-5 (BTA@MOF-5) was doped to the epoxy coating to improve the anticorrosion performance of copper. UV spectrophotometry proved the sustained-release behavior of BTA@MOF-5. Salt spray tests and electrochemical measurements demonstrated the self-healing ability of the composite coating . This novel sustained-release system provides a new strategy for metal protection.

Rose-like sheet zinc phosphate (SZP) was prepared by the induction-calcination method using emulsified paraffin emulsion. The structure of SZP prepared under different conditions was characterized by X-ray photoelectron spectroscopy, X-ray diffractometer, Fourier transform infrared spectroscopy, and Scanning electron microscope. It was added as an anti-corrosive filler to waterborne epoxy-modified acrylic resin. The failure behavior of the coating film was studied by salt spray test and electrochemical workstation. Compared with pure resin, the best neutral salt spray resistance time increased from 24 hours to 336 hours, about 14 times. Besides, the contact angle of the film was measured with a contact angle meter. The results show that SZP can increase the contact angle of the film, improve the water-resistance of the epoxy-modified acrylic resin coating, and prolong the diffusion path of the corrosive medium to the substrate. Therefore, the rose-like sheet zinc phosphate enhances the barrier performance of the coating and can be used as an excellent corrosion inhibitor.

In this study, an environment-friendly titanium (Ti) conversion coating was successfully deposited on the aluminum foil AA 8021 in the solution containing hexafluorotitanic acid (H 2 TiF 6 ), and its morphology, composition, growth process, hydrophilicity and corrosion resistance were characterized by scanning electron microscopy (SEM), atomic force microscopy (AFM), energy dispersive spectroscopy (EDS), X-ray photoelectric spectroscopy (XPS), contact-angle measurements (CAM) and salt spray exposure. The peeling strength between the Ti treated Al foil and the modified polypropylene (PP) film (PP grafted with maleic anhydride, PP- g -MAH) (Al/PP- g -MAH) was measured by T-peeling test. The results show that the Ti conversion coating is a multi-component coating composed primarily of metal oxides (TiO 2 and Al 2 O 3 ) and metal fluoride (AlF 3 ). Ti treated Al foil shows better corrosion resistance than untreated and alkali-cleaned Al foils. The peeling strength of PP- g -MAH film with Ti treated Al foils is approximately 30 times higher than that with untreated Al foils. Thus, Ti treatment is a promising approach to improve the corrosion resistance and peeling strength of aluminum/polymer composite film (Al/P) used in the lithium–ion battery package.

In this work, reduced sulfonated graphene (RSG) containing free amine groups was prepared and modified by 3-aminopropyltriethoxysilane (APTES) and reduction by diethanolamine (DEA). In addition, waterborne polyurethane (WPU) composite coatings were prepared by adding RSG as an anticorrosive filler to WPU. From the results of Fourier transform infrared spectroscopy, X-ray diffraction, and scanning electron microscopy (SEM), it can be found that sulfonated graphene was modified with APTES and successfully reduced by DEA. The SEM images illustrated that RSG was uniformly doped in the WPU. With increasing RSG content, the hydrophobicity of the RSG/WPU films increased due to the strong covalent interaction between RSG and WPU. Finally, the corrosion resistance of the coating was characterized by polarization curves and salt spray tests.

To effectively prevent the diffusion of corrosive ions from the external aqueous environment to the coating, as well as the permeation of ions from the coating into the underlying metal substrate, this study employed a simple spray coating method to construct a diatomite-based bilayer composite coating (referred to as OCDPD) on an AZ31B magnesium (Mg) alloy substrate. This OCDPD coating consisted of a bottom conductive polymer layer, which is a poly(3,4-ethylenedioxythiophene)-loaded diatomite/epoxy resin coating (PD), and a superhydrophobic top layer, which is an octadecyltrimethoxysilane modified CeO 2 @diatomite/epoxy resin coating (OCD). The as-prepared bilayer composite coating exhibited superior superhydrophobicity and self-cleaning capabilities, achieving a corrosion inhibition efficiency of 99.11 % after 168 h of immersion in a 3.5 wt% NaCl solution. Additionally, the OCDPD coating exhibited higher stability in salt spray tests compared to both single-layer coatings (OCD and PD). This study not only demonstrates the exceptional efficacy of the innovative composite coating in protecting Mg alloys from corrosion, but also provides a novel perspective on integrating conductive polymer coatings with superhydrophobic coatings as a comprehensive strategy for corrosion protection .

This study fabricated two composite anticorrosion coatings based on a waterborne epoxy resin matrix, incorporating TC4 alloy powder and TiO2 nanoparticles, respectively, with mineral powder hybridization to enhance performance and reduce material costs. Salt spray testing demonstrated that both systems maintained stability in corrosive environments for over 30 days. However, the TC4-based coating exhibited local edge warping on day 10, indicative of insufficient interfacial adhesion and structural instability. In contrast, the TiO2 composite coating retained structural integrity throughout the test period, demonstrating superior corrosion resistance. Characterization analyses (SEM, TEM, EDS, FTIR, UV–Vis) revealed that TiO2 particles achieved better dispersion and interfacial binding capacity, effectively minimizing pore formation and structural defects. The dense oxide layer on TiO2 surfaces amplified the “maze effect,” significantly inhibiting corrosive medium penetration. Cross-cut adhesion testing and impact resistance evaluation further confirmed the TiO2 system's advantages in interfacial bonding strength and mechanical robustness over the TC4 counterpart. Collectively, the TiO2–mineral hybrid coating demonstrates superior comprehensive protection properties and greater engineering application potential, offering a novel strategy for designing cost-effective, high-performance waterborne epoxy anticorrosion materials.

Magnetic metal absorbers will inevitably suffer from corrosion and aging failure in actual application environments (air, salt spray, acid/alkali, etc.), resulting in serious deterioration of their performance. Using inert, densified materials to modify absorber surface is an effective and feasible solution. Herein, a core-shell structure carbonyl iron composite absorbent (CIP@2-MI/MBI/EP) was prepared by in-situ polymerization with 2-methylimidazole (2-MI), 2-mercaptobenzimidazole (MBI), epoxy resin (EP) as the precursor, and carbonyl iron powder (CIP) as the core. The core-shell structure has enhanced both of corrosion resistance and microwave absorbing performance due to the effect of alleviating the intrusion of corrosive media and low dielectric characteristics of the corrosion inhibitors MBI and EP. The results of electromagnetic parameter test exhibited the minimum reflection loss(RL) of the modified absorbent at 13.78 GHz is -69.57 dB, and the thickness is only 1.65 mm. Electrochemical tests revealed the corrosion potential (E corr )of the composite powder shifted positively from -0.680 V to -0.012 V compared to original CIP. The corrosion current (i corr ) decreased from 59.1 μA/cm 2 to 0.1562 μA/cm 2 , and the annual corrosion rate (CR) decreased by 2 orders of magnitude to 0.0223 mil/year. These results attest to the exceptional corrosion resistance of the composites. In addition, the results of salt spray experiments revealed that the morphology and composition of CIP@2-MI/MBI/EP absorbers remained largely unchanged after 720 H salt spray test. Meanwhile, the acid resistance test (PH=1) further demonstrated the outstanding anti-corrosion performance of the composites. The research offers a new option for the development and design of high-efficiency microwave absorbent with robust corrosion resistance.
