ZL205A aluminum alloys are favored for essential structural components in marine and aerospace sectors because of their superior strength-to-weight ratio. Yet, their vulnerability to corrosion in severe marine conditions presents a notable challenge. Although Wire Arc Additive Manufacturing (WAAM) enables the production of complex ZL205A components, maintaining their corrosion resistance is still a critical concern. This research explores the combined impact of Friction Stir Processing (FSP) and multidimensional nano-reinforcement on the microstructure and corrosion resistance of ZL205A thin-walled parts produced via WAAM. ZL205A thin-walled components, fabricated using Cold Metal Transfer (CMT)-based WAAM, underwent FSP, both with and without BNNS@Al 2 O 3 multidimensional nanomaterials. Our findings indicate that FSP considerably refines the grain structure and reduces the porosity typical of the WAAM process. Incorporating BNNS@Al 2 O 3 nanomaterials during FSP significantly enhanced grain refinement. These nanomaterials formed a network-like barrier within the matrix, effectively isolating the aluminum alloy from corrosive agents. The optimized microstructure results in significant corrosion resistance improvements; nano-reinforced specimens showed a 23-fold decrease in corrosion weight loss rate under salt spray conditions and a 352.58 % increase in equivalent resistance compared to traditional cast ZL205A. The findings highlight the potential of integrating WAAM, FSP, and multidimensional nano-reinforcements to develop high-performance ZL205A components with enhanced corrosion resistance, facilitating broader application in demanding environments.

Zn coating is a typical anti-corrosion coating for carbon steel. Considering the sacrificial nature of Zn coating, it is essential to enhance the corrosion resistance for the long-term performance in the practical application. In this work, two-dimensional carbon nanoplatelets (2D-CNs) with nanometer thickness (∼100 nm) and ultra-large lateral size (10–40 μm) and Mn element have been successfully co-deposited with Zn onto low carbon steel by a simple electrodeposition method. Results show that the Zn-Mn/2D-CNs composite coating is composed of Zn phase, ZnMn 3 phase and a small number of 2D-CNs. The Zn-Mn/2D-CNs composite coating exhibits a modified surface quality with ultrafine grains and smaller roughness (Ra = 176 nm, Rq = 131 nm) when compared with that of Zn coatings (Ra = 798 nm, Rq = 684 nm). Besides, the inert 2D-CNs within the composite coating can act as the corrosion barriers. Therefore, the Zn-Mn/2D-CNs composite coating has excellent anti-corrosion performance, owning the lowest corrosion current densities i corr (9.2 μA cm −2 ) and maximum coating resistance R coat (1.2 kΩ·cm −2 ) and charge transfer resistance R ct (3.5 kΩ·cm −2 ), associated with its modified microstructure, Mn element with passivation property, and 2D-CNs barriers. These results demonstrate the desirable potentiality of inert 2D carbon materials in the electrodeposition of Zn-based coating for improving the corrosion resistance.

Zn(002) has been proven as a dendrite-free anode for Zn batteries. However, stable Zn plating/stripping behavior at an areal capacity exceeding 5 mAh cm −2 has remained unfulfilled so far. In this study, we show that the planar deposit on pure Zn (002) substrate is loosely stacked with high corrosion tendency by the aqueous electrolyte, the key obstacle to achieving considerable efficiency under high-capacity working conditions. To mitigate the side reactions, we introduce an alloying approach by combining monocrystalline Zn(002) with eutectic Al and Cu. The alloying strategy enhances the electrostatic interaction between deposits and substrate, favoring a dense-packed deposition morphology with improved corrosion resistant ability. Solid solution property of Al and Cu in Zn matrix also ensures the structure stability during repeated plating/stripping cycles. As a result, significant extension in cycle life of Zn alloy (002)-based symmetric cells even under 50 mA cm −2 and 25 mAh cm −2 and performance with high utilization also achieves a leading level without extra methods on surface protection. The modified Zn alloy (002) anode induces high anode utilization, paving the way for Zn batteries to meet the requirements of practical applications.

The use of graphene-based materials as anticorrosion coatings to protect metals is always a topic of discussion. In this work, silicon nitride (Si3N4) was aminated to improve its water dispersibility. Then it is attached to the graphene oxide (GO) surface to improve compatibility with epoxy (EP) resin as well as conductivity. The results of Fourier transform infrared (FTIR) spectroscopy, transmission electron microscopy (TEM), scanning electron microscopy (SEM), X-ray photoelectron spectroscopy (XPS), and zeta potentials test analyses indicated that Si3N4–NH2@GO with a layer-point structure has been successfully prepared. The corrosion resistance of the composite coatings was characterized by electrochemical impedance spectroscopy (EIS) and polarization curve analysis, and the wear resistance of the composite coatings was tested by friction and wear tests. The results showed that 1.0% Si3N4–NH2@GO has excellent corrosion and wear resistance. The use of Si3N4–NH2@GO layer point structures in this study broadens the way for GO applications.

Octaglycidyldimethylsilyl polyhydric silsesquioxane (OG-POSS) in coordination with tetraethyl orthosilicate, tetrapropyl orthosilicate and tetrabutyl orthosilicate mixed solution was applied to the bonding of metal substrate and silicone resin thermal protective coating. The influence of OG-POSS addition on the interface of primer was systematically investigated by means of scanning electron microscope (SEM), salt spray test, thermogravimetric infrared spectroscopy (TGA-IR) and back temperature test. Results showed that the addition of OG-POSS favored the formation of a silane film of the primer, resulting in a more compact and continuous film. At the same time, the silane film had excellent corrosion resistance and adhesion, with a maximum adhesion strength of about 1.42 MPa. In addition, OG-POSS provided a unique Si-O-Si cage structure in the primer, which improved the ablation resistance of the interface layer, preventing the degradation and peeling of the coating in harsh environments.

The realization of seawater electrolysis requires high-performing anode materials that should possess good catalytic activity, stability, and specificity for the oxygen evolution reaction (OER) as well as high resistance toward chloride corrosion. Herein, the design of a multilayered oxygen-evolution electrode is reported to meet the multiple needs of anode material for saline water splitting. The multilayered electrode is synthesized through direct thermal boronization of commercially available NiFe alloy plate with boron powder, followed by electrochemical oxidation. And this electrode is composed of the surface oxidized NiFeBx alloy layer, the NiFeBx alloy interlayer, and the NiFe alloy substrate. The boron species are present in the form of metaborate in the outermost oxidized NiFeBx layer, and their existence is conductive to the generation and stabilization of the catalytic active phase γ-(Ni,Fe)OOH. The introduction of NiFeBx interlayer effectively prevents the excessive oxidative corrosion of the anode material in the electrolyte containing chloride ions.

A simple, efficient and low-cost method is proposed to prepare surfaces with reversible superwettability and excellent corrosion resistance. Superhydrophobic surfaces are successfully obtained on the copper alloys by etching, heat treatment, and then stearic acid modification, exhibiting extraordinary water repellence with a static contact angle of 159.7 ± 1.2°, and a sliding angle of 3.1 ± 0.6°. The reversible transition of the superwetting state are successfully achieved. The surface can be turned into a superhydrophilic state by simple heat treatment. And then, it can be turned into a superhydrophobic state by re-modification. Meanwhile, the effects of etching time and heat treatment temperature on wettability are also studied. Finally, the corrosion resistance of the copper alloys and the durability under various extreme conditions are investigated. The results show that the prepared superhydrophobic copper alloys have excellent corrosion resistance with a corrosion inhibition rate of 98.83% and superior durability, which will further expand its practical applications.

Geopolymers have attracted extensive attention in the marine environment because of its special reticulate nanostructure. Gel evolutions of copper tailing-based green geopolymers were studied under air, deionized water, seawater, freeze–thaw cycle and carbonization environments. Their mechanical properties and microstructures were characterized by compressive strength measurement, X-ray diffraction (XRD), Fourier-transform infrared spectroscopy (FTIR), nuclear magnetic resonance (NMR) and scanning electron microscopy (SEM). It was found that the deionized water and natural marine water exposure promoted the evolution degree of geopolymers and improved their compressive strength, while exposure to the carbonization environment weakened the gel evolution and decreased the cross-linking degree of the Sodium aluminosilicate hydrate (N-A-S-H)gel structure, resulting in a decline of compressive strength. The geopolymer exposed in the freeze–thaw cycle exhibited the worst deterioration due to the expansion caused by the crystallization in the geopolymer. These results are essential and beneficial to further understanding the gel formation process in various marine environments and could promote the investigation of green concrete.Keywords:geopolymer;marine concrete;compressive strength;carbonization;corrosion resistance

Pipeline steels are among the most common engineering materials and are used extensively in various industries. Therefore, it is essential that these materials are hydrophobic and corrosion resistant . Herein, a simple method to prepare a superhydrophobic coating on X65 steel is proposed. Firstly, the black oxide coating (BO) was grown in situ on X65 steel surface, utilizing its morphology advantage to build the micro-nano structure, where they showed a water contact angle (WCA) of 158°. After fluorination, the WCA of the coating increased to 163°. The prepared superhydrophobic samples were exposed to air and salt spray test for a 30-day durability study, where the long-lasting superhydrophobicity of the coating demonstrated its wide applicability. In addition, the coating also exhibited excellent corrosion resistance and self-cleaning property. This work provides a simple and low-cost technique for designing superhydrophobic coatings on steels.

Bone defect repair relies on the reconstruction of the maxilla and alveolar bone. Magnesium and its alloys offer great potential as implant materials due to their biocompatibility and mechanical properties, but their rapid degradation limits clinical use. This study developed an MgF 2 -polydopamine-Epigallocatechin gallate (MgF 2 -PDA-EGCG) composite coating on AZ31B magnesium alloy using hydrofluoric acid fluorination and layer-by-layer self-assembly. The coating’s corrosion resistance, biocompatibility, antibacterial properties, and osteogenic potential were evaluated. Characterization showed a dense, uniform coating (∼5.6 ± 0.2 μm thick) that significantly improved corrosion resistance. In a seven-day hydrogen evolution test and long-term immersion study, the P2E0.5 coating reduced hydrogen release (0.57 ± 0.16 mL/cm 2 ) and mass loss (7.31 ± 0.83%). Biocompatibility tests (CCK-8 and live/dead staining) confirmed no cytotoxicity. Antibacterial tests showed inhibition rates of 75.8% for Escherichia coli and 83.43% for Staphylococcus aureus. ALP activity was 188.18% ± 37.56% of the control, indicating enhanced early osteogenesis. In summary, the MgF 2 -PDA-EGCG coating improves the corrosion resistance and biological properties of AZ31B magnesium alloy, supporting its potential for biomedical implants.

Magnesium (Mg)-based biometals are promising candidates for next-generation biodegradable implants in bone regeneration. However, their rapid biocorrosion in physiological environments necessitates protective coatings to enhance corrosion resistance and osteogenesis. Conventional hydrophobic modifications, while effective in mitigating corrosion, often impair biological responses, hindering tissue integration and bone regeneration. Inspired by the architecture of cell membranes, we developed a novel layered octacalcium phosphate (OCP) coating intercalated with a hydrophobic alkyl-phosphate-surfactant bilayer, imparting Mg biometals with enhanced bioactivity and resistance to biocorrosion. Additionally, an MgF 2 transition layer with a mechanically interlocking architecture is fabricated via an in situ growth approach, ensuring the long-term structural integrity and interface stability of the hybrid coating. Compared with conventional coatings, the resulting intercalated organic/inorganic hybrid coatings exhibit exceptional mechanical robustness, remarkable corrosion resistance, and bioactivities conducive to cellular adhesion and proliferation . In vivo implantation tests further revealed a significantly reduced corrosion depth (~ 1.1 μm), minimal inflammatory response, and reduced fibrous encapsulation (~ 65.2 μm), demonstrating its clinical potential. This work pioneers a bioinspired strategy for multifunctional inorganic/organic hybrid coatings, advancing the clinical application of Mg-based implants in osteogenesis. Graphical abstract

Polyaniline (PANI) was covalently linked with hexagonal boron nitride (BN) using p-aminobenzoic acid (ABA) to obtain a PANI-BN powder. The PANI-BN/EP coating was applied on hot-dip galvanized steel, which exhibited remarkable corrosion resistance. Electrochemical test results showed that the impedance modulus in the low-frequency region of PANI-BN/EP was maximum after soaking in NaCl solution (3.5 wt.%) for 72 h compared with other coatings. The outstanding corrosion resistance of the PANI-BN/EP coating was primarily attributed to the synergistic effect of BN and PANI.
