Summary: The use of a pyrolytic carbon (PyC) coating prior to the fabrication of a silicon carbide (SiC) coating on carbon/carbon (C/C) composites helps to mitigate the negative effects of siliconization erosion, leading to an increase in flexural strength retention and better oxidation resistance. The presence of PyC coating allows for the fabrication of a compact SiC coating without silicon phase, resulting in improved performance under dynamic and static oxidation conditions at different temperatures.

Summary: The SiC coating on C/C composites was studied with rough laminar (RL) and smooth laminar (SL) pyrocarbon matrix separately. The results showed that the RL-SiC coating had smaller residual stress, higher hardness, and elastic modulus compared to SL-SiC, which improved its resistance to cracking and oxidation.

Summary: This study investigates the ablation behavior and protection mechanism of HETMB2-SiC-Si composite coating on C/C composite under ultra-high temperature conditions. The results show that the composite coating exhibits excellent resistance to ablation and oxidation protection. The formation of a differentiated oxidation scale with enhanced high-temperature thermally-stable and defect-sealing ability is attributed to the selective oxidation and phase separation mechanisms.

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.
