Summary: This study investigated the performance of C/C-SiC brake discs under extreme conditions and revealed the friction interface evolution and anti-fading mechanism of the discs. The results showed that the C/C-SiC brake discs performed well at high temperatures, with a high maximum temperature and low decay rate. Compared to iron-based brake discs, the C/C-SiC discs had increased friction coefficient and decreased wear rate. The formation of a continuous friction film during braking contributed to the excellent performance of the discs. Additionally, the C/C-SiC brake discs exhibited stable and sufficient braking force during emergency braking.

Summary: In this study, the radiation-induced microstructure evolution of M55J and T300 carbon fibers in C/SiC composites was investigated. Both carbon fibers exhibited axial shrinkage after irradiation, with M55J fibers showing slightly lower shrinkage compared to T300 fibers. Detailed microstructure characterization revealed disruptions in the graphite structure of both carbon fibers due to ion irradiation. The ordering degree of T300 fibers increased at low doses and decreased at higher doses, and possible mechanisms for the healing process in T300 fibers were discussed.

Summary: Nano-porous titanium carbide (TiC) coating was synthesized in-situ on silicon carbide (SiC) fiber substrate using titanium tetrachloride (TiCl4) vapor. The coating consisted of TiC nanograins and the nanopores were formed by lateral stack growth. The composition and morphology of the coating were controlled by the supersaturation of gaseous reagents at the boundary layer. The flexibility of the SiC fiber was preserved by the optimized TiC coating. Lastly, a SiCf/SiC mini-composite with nano-porous TiC interphase was prepared, exhibiting fiber pull-out and interphase fracture on the fracture surface.

Summary: C/C-ZrC-SiC composites with La-doped ZrC-SiC-ZrSi2 coatings containing different La contents were prepared. The ablation behaviors of the composites under oxyacetylene flame were studied, and the effects of La2O3 addition on the microstructure and phase composition evolution were investigated. The results showed that the composites with 15 wt% La2O3 exhibited better ablation resistance due to the formation of a dense oxide layer consisting of m-ZrO2, t-ZrO2, and Zr0.9La0.1O1.95 phases.

Summary: SiO2 interface was introduced into SiCnws/BSAS ceramic to enhance high-temperature electromagnetic absorption. By changing the SiO2 content, the interface structure was tailored, leading to increased polarization loss. The optimized SiCnws/SiO2-BSAS ceramic demonstrated enhanced electromagnetic absorption at 873 K with an effective absorption bandwidth of 4.1 GHz. The electromagnetic absorption mechanism was analyzed from the perspectives of electron transport and space charges. This heterointerface design strategy offers a new method for developing high-temperature electromagnetic absorption materials.

Summary: The preparation of micro/nano periodic surface structures using femtosecond laser machining technology has been a hot topic in recent years. In this study, the formation and evolution of micro/nano periodic ripples on 2205 stainless steel were investigated. Different types of ripples were generated through single spot irradiation with fixed laser fluences and various pulse numbers. The morphologies of the ripples were analyzed and the underlying mechanisms were discussed. It was found that the presence of nano holes/pits played a crucial role in the formation and evolution of the ripples. Additionally, a new microstructure called the pea pod-like structure was discovered, and it provided a possible explanation for the formation and evolution of the micro/nano periodic ripples.
