Summary: Electroless and electroplated single-layer Ni and multilayer Ni/Pd/Au were used as surface finishing materials for automobile device substrates. The electroless Ni and multilayer Ni/Pd/Au exhibited better corrosion resistance compared to their well-crystalline electroplated and electroless counterparts, respectively, when exposed to various gaseous SO2 concentrations. Galvanically displaced Pd and immersion Au provided more diffusion paths for corrosion product growth on the electroless Ni/Pd/Au surface, leading to enhanced corrosion resistance.

Summary: The electroless plating and electrodeposition process was used to prepare a Ni-Cu-P bilayer composite film with hydrophobic properties on the Ni-P film. The introduction of Cu inhibits the growth of cellular structures, increases nucleation points, and improves the microstructure of the Ni-Cu-P films. The Ni-P/Ni-Cu-P bilayer composite film has a pinecone-like convex structure, reduces surface energy, exhibits hydrophobicity, and effectively resists external impurities and fouling, improving corrosion resistance.

Summary: This study investigated the influence of fluoride ions on the growth of PEO/Ni-P composite coating on magnesium alloy AZ31B. It was found that fluoride ions can increase the thickness and compactness of the PEO coating but hinder direct EN plating, with Ni-P nodules selectively nucleating in the micro-pores of the PEO layer. The PEO/Ni-P composite coating provides superior corrosion protection to the magnesium substrate.

Summary: This study investigates the addition of fluoride to the electroless nickel-phosphorus plating solution to improve the corrosion resistance of MAO-coated AZ31B magnesium alloy. Fluoride reacts with Ni2+ ions and the MAO coating to form interphases, which enhance bonding and corrosion resistance. The presence of fluoride in the plating solution results in a more corrosion-resistant coating. The composition, structure, and morphology of the coatings are characterized using various analytical techniques, and their corrosion resistance is evaluated using different tests.

Summary: In this study, Ni-modified graphene powders were synthesized by electroless plating method and used to prepare Ni60-Ni@Gr composite coatings, enhancing the application of graphene in laser cladded coatings.

Summary: Composite electrodeposition was used to prepare Zn-Ni-B4C composite superhydrophobic plating with hierarchical micro/nanostructures on Q235 steel. The addition of micron B4C particles promoted the formation of protrusion structures, while the change in current density promoted the development of hierarchical rough structures. The plating exhibited excellent superhydrophobicity with a water contact angle of 159 degrees and showed good corrosion resistance in a 3.5 wt% NaCl solution.

Summary: The traditional aqueous electrolyte used for studying soil-related corrosion in laboratories does not accurately represent the physical features of soil. This article introduces a semi-solid agar system that can replicate the structure of soil for corrosion study. The results show that the agar system has similar oxygen diffusion characteristics to soil, weakening the cathodic activity of steel specimens and leading to different corrosion characteristics compared to aqueous electrolytes. The solid nature of agar outperforms aqueous electrolytes in simulating soil-related corrosion responses at the laboratory scale.

Summary: The microstructure of the Ti-4Al-6Mo-2V-5Cr-2Zr alloy is highly sensitive to aging temperature and time, which directly affects its mechanical properties. The effects of aging parameters on the microstructure and tensile properties of the alloy were investigated by varying the aging temperature from 520 to 640°C and time from 2 to 8 hours. It was found that the volume fraction and shape of the secondary α phase (as) in the β matrix changed with aging temperature and time, and a higher volume fraction of the as phase resulted in higher strength. The strengthening mechanism of the as phase was also clarified through SEM and TEM observations.

Summary: This work develops a synergistic inhibiting strategy using two distinct aromatic heterocyclic ring systems to protect electro-galvanised steel against aqueous corrosion. The formulated mixture shows an enhanced inhibitory efficiency of 96% after 7-day immersion in a NaCl solution. Surface and electrolyte chemistry analysis reveals a two-step process in the growth of the protective layer, reflecting the sequential responses of each inhibitor's mode-of-action. This synergistic inhibition formulation offers potential to modify corroded ZE surfaces.

Summary: Hydrogen evolution, magnesium dissolution, and electron exchange were monitored in real time during anodic and cathodic polarization of magnesium in 0.1 M NaCl. The anodic charge correlated with magnesium dissolution, while hydrogen formation was independent and led to insoluble magnesium(II) formation. Increased iron impurity promoted hydrogen evolution but was not necessary for the negative difference effect. Electrochemical dissolution occurred across an intact magnesium(II)-based film, while hydrogen evolution occurred in regions where the film breaks down induced by anodic polarization.

Summary: One challenge in using X-ray imaging for post-process inspection of fusion welding is the lack of contrast between the fusion zone and base metal. This study develops novel filler wires with Ce additions to create grayscale contrast for X-ray imaging. The addition of Ce-containing precipitate particles enhances the contrast and enables superior quantitative inspection. This method effectively measures weld penetration by X-ray imaging.

Summary: In this study, two approaches, including TiB2 additions and optimization of LPBF process parameters, were used to suppress the formation of hot cracks in laser powder bed fusion (LPBF) additive manufacturing of 2XXX series Al alloys. High-speed synchrotron X-ray radiography and high-resolution synchrotron X-ray computed tomography (sCT) were used to monitor the LPBF process and measure the volume fraction of defects in the as-built samples. The results showed that adding TiB2 in Al-2139 reduced the volume of cracks by up to 79% and decreased the average length, breadth, and surface area of cracks.

Summary: This article investigates the effect of minor Fe additions on crack elimination in rapidly solidified Al alloy 6060 and provides insights into the underlying mechanism. The results show a decrease in cracking with increasing Fe content, and complete elimination of cracks in the 6060 + 0.5Fe sample. Microscopic analysis reveals the morphological changes of AlFeSi particles in the melt pools, and suggests that bridging of the Al matrix by these particles plays a crucial role in crack mitigation.
