Summary: In this study, CeO2-modified WC-12Co coatings were deposited on a Q345 steel substrate using HVOF spraying, and the oxidation behavior of the coatings was investigated. The results showed that the CeO2-modified coatings exhibited good oxidation resistance below 550 degrees C, and the oxidation mechanism changed at temperatures above 650 degrees C. The oxidation mass gain curves followed a parabolic law initially and a linear law later. The role of rare earth additives during high-temperature oxidation was also determined.

Summary: This study focused on analyzing the microstructure and mechanical properties of cemented carbides fabricated via LMD on different substrates. The results showed that cemented carbide formed on the WC-20Co substrate had higher density and fewer cracks and pores compared to the 45# steel substrate. The smaller grain size in the microstructure of the cemented carbide formed on the 45# steel substrate was possibly influenced by differences in liquid phase point and solid solubility between the two materials.

Summary: In this study, WC-12Co hardmetals with varying MoSi2 content were fabricated using spark plasma sintering, and the effects of MoSi2 concentration on structure, high-temperature oxidation, density, and hardness were investigated. The results showed that increasing MoSi2 content led to decreased oxidation resistance and the formation of an oxide layer in the hardmetals, but it also helped reduce crack formation in the oxide layer.

Summary: It has been found that the particle size of Ni-Al composite powders plays a crucial role in controlling the exothermic reaction for the formation of Ni-Al intermetallics during plasma spraying. Larger powder particles make it difficult for the reaction to complete, while smaller powder particles allow the exothermic reaction to occur rapidly, contributing to the development of the self-bonding effect in the coatings. The higher droplet temperature resulting from the exothermic reaction contributes to the adhesive or cohesive strength of the coatings.

Summary: In this study, the oxidation kinetics of 430L porous support in PMS-SOFCs was investigated, showing a 1% mass gain after 500 hours of exposure at 650 degrees C due to the formation of a continuous Cr2O3 scale. Diffusion of elements across the interface of the anode and support was hindered by thin and continuous scales, with less than 1 µm thickness after 500 hours of oxidation. The decrease in maximum power density after 500 hours of oxidation was attributed to the formation of a continuous Cr2O3 scale and an increase in ohmic and polarization resistance.

Summary: By introducing large-sized WC17Co particles into TC4 powder during cold spray, a forging/hammering effect was achieved to densify the deposited TC4 coatings, leading to improved wear resistance and corrosion protection. The addition of WC17Co reduced porosity in composite coatings, with the 80 vol.% WC17Co-TC4 coating showing the best corrosion resistance and 10 times higher wear resistance compared to pure TC4 coating. Adjusting the WC17Co content can effectively enhance the protective properties of the coatings.

Summary: SULC technology has great potential in underwater in-situ manufacturing/remanufacturing, allowing for the preparation of iron-based planar coatings with solidification structure distribution. The size and stability of the local dry region above the deposition point is influenced by the powder-feeding gas flow rate, while the laser power and powder-feeding rate are key factors in compensating for energy dissipation. Due to the local temperature gradient in SULC, the coating exhibits distinct solidification structure distribution.

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.

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.
