Summary: The corrosion performance of NiCr and NiCrBSi coatings produced by APS, HVOF, and HVAF was investigated using electrochemical measurements and immersion tests. The NiCr coatings outperformed the NiCrBSi coatings in terms of corrosion resistance. The impact of the coating process on corrosion resistance was lower compared to the choice of materials, NiCr or NiCrBSi. All the coatings exhibited a tendency towards passivation but suffered from localized corrosion, primarily in heterogeneous areas of the coatings.

Summary: This research article explores the corrosion behavior of ECAP and annealed commercial pure aluminum. The ECAP process showed significant grain refinement and high-angle grain boundary. ECAP with a new die resulted in reduced friction, minimized recrystallization, and refined grain size. The corrosion studies revealed improved corrosion resistance with increasing ECAP passes and the formation of a diffusion layer in ECAPed samples.

Summary: The effect of aluminum on the corrosion resistance of structural steels varies depending on the conditions. In neutral cyclic salt spray conditions, aluminum enhances corrosion resistance by promoting the formation of a stable protective layer. However, in immersion conditions, the addition of aluminum leads to decreased corrosion resistance due to increased electrochemical activity and the formation of local corrosion sites.

Summary: Corrosion testing with gel electrolytes has gained attention in recent years for its non-destructive and in situ electrochemical measurements. Gel electrolytes provide an opportunity to prevent infiltration of microstructural features in thermal spray coatings. The corrosion behavior of stainless-steel AISI 316L coatings deposited on different substrates was analyzed in both aqueous and gelled 3.5% NaCl electrolytes, demonstrating that gel electrolytes can mimic the corrosion attack caused by aqueous electrolytes.

Summary: In this study, two leachable anticorrosive pigments, cerium 4-hydroxycinnamate (Ce(4OHCin)3) and strontium zinc phosphosilicate (SZP 391), were incorporated separately into model organic coatings to protect the structural integrity of AA2198-T851 aluminum alloy under neutral salt spray and immersion test conditions. The protective films formed through the dissolution and release of inhibitor clusters from the coatings, which provided channels for the transport of inhibitive species. The protective films revealed a monolayer structure, and their inhibitive properties were confirmed by increased impedance modulus of the substrate.

Summary: The corrosion behavior and corrosion rate of friction stir welded AZ31B magnesium alloy and 6N01 aluminum alloy dissimilar joints were studied using real-time imaging, potentiodynamic polarization, EIS, and hydrogen evolution tests. The corrosion rate was found to increase in the order of Al base metal < Mg base metal < stirred zone. The galvanic coupling of the Mg phase to other phases enhanced the corrosion of both base metals, and intense corrosion at BM-AZ31B elevated the interfacial pH due to water reduction on the cathodic particles of BM-6N01.

Summary: This study investigates the influence of biologically relevant ions on the corrosion of zinc in physiological fluids. Electro-chemical techniques were used to study the degradation of pure zinc exposed to different physiological electrolytes containing chlorides, carbonates, sulfates, and phosphates. The most aggressive ions are chlorides, while carbonates and phosphates reduce the corrosive attack and sulfates disrupt the passive layer of zinc, altering its corrosion behavior.

Summary: Suspension feedstock has been shown to improve the performance of thermal sprayed coatings compared to sub-micron and nanosized powder feedstock. The use of a powder-suspension hybrid feedstock in the HVAF spraying process demonstrated higher hardness and better wear resistance in the coatings. The incorporation of a secondary carbide phase in the IN-625 matrix did not compromise its corrosion performance, showing potential for enhanced performance in harsh environments.

Summary: This study introduces a unique melting strategy in electron beam-powder bed fusion to tailor the grain morphology of Alloy 718 from columnar to equiaxed. By controlling the local solidification conditions and motions within the melt pools, the transition in grain morphology was achieved. Four different microstructures were identified, with the typical texture being <001>, and shrinkage defects and cracks were reduced with a decrease in areal energy input. Hardness was increased due to the growth of gamma precipitates and high grain boundary density in the fully-equiaxed grain morphology.

Summary: In this study, a unique linear melting strategy coupled with a specific selection of process parameters in EB-PBF was used to facilitate the columnar-to-equiaxed grain structure transition in Alloy 718. Site-specific melting using the line order number (LON) function affected cooling rate, temperature gradient, grain morphology, and texture. High LON resulted in a large equiaxed grain zone with a random texture, while a fixed LON with high areal energy density led to a strong texture.

Summary: The corrosion behavior of Fe-60 and Fe-83 ribbons in 0.6 M NaCl was studied. Fe-60 exhibited a local corrosion mode and formed a stable passivation film with higher corrosion resistance, while Fe-83 showed a combination of local and global corrosion modes and had lower corrosion resistance. Controlling the precipitation of nanocrystalline phases and increasing the POx content in the passivation film significantly improved the corrosion resistance of Fe-based glassy alloys.

Summary: In the study of BM-SCO and HSCO thin films, it was found that H vacancies tend to prefer sites near the external surface or oxygen vacancy channels (OVCs), while H interstitials prefer sites of oxygen on a layer that contains six-fold coordinated Co. These findings not only enrich the understanding of complex surface phenomena of defect formation but also provide an explanation for the reversibility during phase transformation.

Summary: In this study, a potential platform to enhance Raman scattering and increase the number of observable Raman modes in monolayer transition metal dichalcogenides (TMDs) was proposed. The platform consisted of large-scale arrays of gold micropillars (MPs), which were able to enhance the Raman intensity of TMDs and make difficult-to-detect Raman modes observable. The platform showed great industrial advantages and wide applicability due to its low cost, simple process, large controllable area, and short process time.
