Summary: Enhancement of wear resistance of components used in fast reactors is necessary for long service life. Plasma nitriding is a promising technology to improve hardness and wear resistance. This study characterizes the chrome nitrided SS316L casing ring used in secondary sodium pump and assesses its stability under long term sodium exposure. The results show successful chrome nitriding and retention of the nitrided layer after sodium exposure, although there is a slight decrease in hardness.

Summary: The wear resistance of 304 stainless steel was enhanced by depositing a FeCrAlNbNi alloyed zone (AZ) on its surface using laser surface alloying technology. The AZ showed a dense and fine structure with equiaxed dendrites as the main microstructure. The average microhardness of the AZ was about 2.6 times higher than that of the substrate due to the presence of iron compounds and iron-based solid solutions. The friction and wear performance of the AZ was better than that of the substrate at various temperatures, with the highest abrasion resistance observed at normal temperature. However, at elevated temperatures, the wear resistance initially decreased and then increased, with the formation of an Al2O3 layer at 600 degrees C greatly improving the wear resistance.

Summary: In this study, conventional gas metal arc welding (GMAW) setup was successfully used to develop SiC-reinforced AISI 304 stainless steel (ASS) clad layer on low carbon steel (LCS) substrate. The characteristics of the clad bead and dilution were influenced by GMAW voltage and consumable wire feed rate (CWFR). The SiC-reinforced clad layer showed a uniform distribution of fine SiC particles and the formation of different hard intermetallics, resulting in improved microhardness and wear resistance compared to the steel substrate.

Summary: The study investigated the cracking susceptibility, microstructures, and wear resistance of coatings with different dilution rates by altering the processing parameters. It was found that the dilution effect of the eutectoid steel substrate increased with the increase of laser beam power, leading to composition deviation of coatings. Microhardness of the coatings increased with the dilution rate but excessive dilution resulted in severe cracking defects. The optimized cladding coating with a dilution rate of about 48% exhibited improved microhardness and wear performance due to increased carbon content.

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.
