The corrosion of positive grid alloys is important for determining the service life of lead-acid batteries (LABs). Herein, we prepared a series of PbCaSnAl-M (M = Mg, Sr, Ba) alloys by an induction melter and systematically investigated the effect of Mg, Sr and Ba on their microstructures and corrosion resistance. The results show that the average grain size of PbCaSnAl-Mg reduces from 14.56 μm to 11.96 μm, and the average grain size of PbCaSnAl-Sr and PbCaSnAl-Ba increases to 25.95 μm and 39.17 μm, respectively. The addition of Sr and Ba reduces the corrosion rate of PbCaSnAl alloys from 0.366 mg h −1 cm −2 to 0.258 and 0.289 mg h −1 cm −2 , respectively. The increase corrosion resistance is due to the Sr and Ba change the microstructures of the corrosion layer and improve the densification of the corrosion layer.

Dy 2 TiO 5 ceramics with small grain size range of 1.5–3 μm were successfully prepared by microwave sintering method. The phase composition, microstructure, thermal expansion, stability, corrosion resistance and neutron absorption properties of Dy 2 TiO 5 ceramics were investigated. The results show that Dy 2 TiO 5 ceramics possess high mechanical properties due to the small grain size, with a microhardness of 12.26 GPa. The addition of Mo significantly reduces the thermal expansion phenomenon of the sample. The oxide film formed on the surface of the Dy 2 TiO 5 ceramic enhances its excellent corrosion resistance. In addition, the Dy 2 TiO 5 ceramic shows excellent neutron absorption with 87.34% neutron absorption and over 94% thermal neutron absorption in 8 cm thick particles.

Designing suitable surface structures is crucial to achieving long-lasting superhydrophobic properties. In this study, laser marking was utilized to fabricate micron groove arrays, creating the LM sample, which was then coated with a nickel nanocone-shaped structure through electrodeposition, forming the LME sample. Organic modifications were applied to both samples to increase their hydrophobicity. The surface morphology and cross-section structure of the coatings were analyzed in detail, and contact angle measurements indicated the presence of an air layer. A thorough analysis was conducted to compare the hydrophobicity of the laser marked and LME samples, revealing that the LME sample demonstrated exceptional wear-resistant superhydrophobicity. This was validated by various friction wear tests, which were performed using a well-designed testing setup. Moreover, the coating adhesion was assessed through a peeling test, revealing a strong adherence to the substrate. The corrosion resistance of the LME sample was also superior to that of the LM sample, as demonstrated by the results of the corrosion tests. The cost-effective and controllable method of laser marking and electrodeposition used in this study provides a feasible way to develop durable and resistant superhydrophobic coatings on light alloy surfaces.

Developing multifunctional separation membranes, especially composite separation membranes that are corrosion-resistant, fouling-resistant, and easy to collect, has become a new challenge to treating oily wastewater in complex environments. Therefore, superhydrophobic magnetic membranes composed of polystyrene/poly(acrylonitrile)-poly(vinylidene fluoride)/poly(dimethylsiloxane)-iron oxide/titanium dioxide nanoparticles (PS/PAN-PVDF/PDMS@Fe 3 O 4 /TiO 2 ), which possess exceptional corrosion resistance and UV absorption properties, were fabricated through the process of electrospinning. Controlling the doping ratio of Fe 3 O 4 /TiO 2 , composite membranes with excellent superhydrophobicity (156.9°), mechanical properties (3.67 MPa and 75.93 %), and thermal stability (330 °C) were obtained. The membrane demonstrates outstanding corrosion resistance (WCA > 150°) even after being immersed in various corrosive solutions for 120 h. Under visible-ultraviolet irradiation, the membrane has excellent UV absorption and exhibits a significant red-shift phenomenon, providing a certain degree of resistance to fouling. In the presence of a magnetic field, the membrane has a maximum saturation magnetization of 9.98 emu/g, which the magnetic field drive can attract. The oil adsorption capacity of the membrane was 29–112 g/g, which also maintained 88 % of the initial value after ten cycles. In addition, a comprehensive evaluation was conducted to assess the fabricated composite membrane's separation flux, efficiency, and cycle life when exposed to acidic and alkaline corrosive solutions. The results indicated that even after 40 cycles, the membrane's oil–water separation flux and separation efficiency remained at 6971 L.h −1 .m −2 and 97 %, respectively, representing a 24.2 % increase compared to the unmodified membrane. Therefore, the membrane exhibits promising potential for treating oily wastewater in harsh environments.

Superhydrophobic ceria on the aluminum substrate was fabricated, and its corrosion resistance was investigated by different techniques. For example, the so-obtained superhydrophobic sample was immersed into the NaCl aqueous solution, and the variations in the surface wettability as well as the surface morphology were monitored; potentiodynamic polarization in the NaCl aqueous solution was adopted to evaluate its electrochemical corrosion resistance; a droplet of the aqueous solution HCl was dripped onto the superhydrophobic surface, and the corrosion process as well as the surface morphology after corrosion was monitored. The experimental results showed that the superhydrophobic ceria possessed a good corrosion resistance because of the entrapped air in the solid/liquid interface.

Despite the considerable demand for unique non-wetting superhydrophobic surfaces, simple and scalable one step fabrication approach has rarely been established. Herein, we report a convenient one step hydrothermal strategy for fabrication of superhydrophobic 5083 aluminum alloy (AA5083) surface. The spontaneously formed rough micro-structures and water repellent property can be achieved after pentadecafluorooctanoic acid (PFOA) aqueous solution treatment. The surface topography and chemical compositions were studied by scanning electron microscopy (SEM), energy dispersive X-ray spectroscopy (EDS) and X-ray photoelectron spectroscopy (XPS). The co-existence of flower-like micro-structures and abundant -CF 3 and -CF 2 groups after one step PFOA hydrothermal treatment contributes to the improved air-liquid interfacial contact area and the eventual anti-wetting behaviors. The as-prepared superhydrophobic AA5083 surface exhibits excellent water flow repellency, stable self-cleaning ability and favorable corrosion resistance . We believe the convenient and effective one step strategy will inspire the large-scale preparation of multifunctional surfaces for widely application scope.

With the increasing demand for environmental protection, the recovery and reuse of fly ash has attracted more and more attention. In this paper, the fly ash based porous ceramic membrane is modified from hydrophilic to superhydrophobic successfully. Average contact angle and roll-off angle of the modified superhydrophobic fly ash based ceramic membrane are 151.3° and 11.3°, respectively. Additionally, a variety of performances of the prepared superhydrophobic fly ash based ceramic membrane are characterized. Dynamic process of droplets with different initial velocities impacting on the surface of superhydrophobic fly ash based ceramic membrane is photographed by high-speed camera. It is proved that dynamic process of droplet impacting on superhydrophobic surface includes spreading, retraction and partial rebound. Spreading, retraction and solid-liquid contact time of droplets are about 2.9 ms, 11.5 ms and 14.4 ms, respectively. The above data is almost unaffected by impact velocity of droplets. In addition, experiments show that the prepared superhydrophobic fly ash based ceramic membrane has good acid and alkali corrosion resistance , and self-cleaning performance. In this paper, superhydrophobic ceramic membrane prepared by fly ash shows excellent performance and it can provide guidance for the reuse of fly ash.

Colorful aluminum pigments are commercial demand for the pursuit of a range of aesthetic over the last few years. In this study, a general approach for preparation of colored aluminum pigments is reported by two-step process of poly(dopamine) (PDA) encapsulation and dye conjugation. Firstly, the surface of the aluminum pigment was encapsulated by a PDA layer in an alkaline/ethanol environment (PDA@Al), and orthogonal experiments were investigated to explore the optimal reaction conditions. Secondly, using Disperse orange 11 as typical dye, the PDA@Al were colored by the Michael addition reaction between the functional dyes and quinone structures in the PDA layer. The morphology, component and structure of the colored aluminum pigments was characterized by FTIR, SEM , XPS and TG. The results showed that the corrosion resistance and wettability of colored aluminum pigments were significantly improved. This wok provides a new general strategy for the preparation of colorful aluminum pigments with PDA as the protected and functional layer.

Although the formation of plasma electrolytic oxidation (PEO) coatings on aluminum alloys can significantly enhance their service life, they may still suffer from corrosion damage when exposed to harsh environments with strong corrosivity for a long time. In this work, chitosan (CS) was dissolved in four acids, i.e. hydrochloric acid (HCl), citric acid (CA), lactic acid (LA), and acetic acid (HAc), and deposited onto the PEO-coated 5052 aluminum alloy using dip coating method. Scanning electron microscope (SEM), energy dispersive spectrometer (EDS), atomic force microscope (AFM), contact angle (CA) meter, grazing incidence X-ray diffraction (GIXRD), Fourier transform infrared spectrometer (FTIR), and electrochemical workstation system were used to explore the enhancement of the corrosion resistance of PEO-coated 5052 aluminum alloy by application of CS film prepared in different solvent acids. The results showed that the interactions between chitosan and acid ions affects the uniformity, hydrophobicity , thickness and surface roughness of the CS/PEO coating. The HAc-CS/PEO coating had the lowest surface roughness of 32.4 ± 3.9 nm, the largest contact angle of 85.7 ± 2.0°, and the thickest CS film of 20 μm, which significantly improved corrosion resistance of PEO-coated aluminum alloy.

Inconel 625 + x Al ( x = 0, 2.5, 5.0, 7.5, 10.0) alloy coatings were prepared by laser cladding. The addition of Al promoted the formation of the BCC phase, which changed the coating microstructure from an FCC + δ phase + Laves phase to FCC + BCC + δ phase + Laves phase. Inconel 625 + 2.5 Al alloy showed the greatest corrosion resistance among all samples. The formation of an Al 2 O 3 film improved the corrosion resistance of the coating, but excess Al decreased the Cr 2 O 3 content in the film, which decreased the corrosion resistance of the coating. Increasing the Al content aggravated the lattice distortion and improved the solid solution strengthening effect, while also increasing the amount of BCC phase, which improved the coating hardness. After adding Al, the Inconel 625 + x Al alloy coatings displayed strong plastic deformation resistance, and their wear resistance was improved due to the presence of a hard phase.

In this study, a composite coating of polycaprolactone layer and polydopamine-cyclodextrin (β-CD)/naringenin (NG) was prepared on the surface of a micro-arc oxidized (MAO) pretreated magnesium alloy by a two-step method. The findings demonstrate that the composite coating exhibits favorable corrosion resistance, biocompatibility, photo-thermal antimicrobial, and bone-enhancing characteristics. Compared with the MAO coating, the corrosion rate of the composite coating was significantly reduced from about 0.087 mm/y to 0.066 mm/y. The antimicrobial efficiency of the coating against Staphylococcus aureus (S. aureus) and Escherichia coli (E. coli) under 808 nm laser irradiation was found to reach 93 % and 99 %, respectively. Furthermore, in vitro cytotoxicity assays, dead and live cell staining, and immunoblotting analysis showed that the coating exhibited favorable biocompatibility and osteogenic activity. This novel coating may have good application prospects in the treatment of osteoporosis-related fractures.
