“…The thermal expansion compatibility between SiC and C/C composite materials is noteworthy. Zhen et al employed a slurry spray combined with chemical vapor reaction to fabricate SiC coatings on the surface of C/C-SiC composite materials [4]. Li et al utilized a three-step method to prepare SiC/SiC-MoSi 2 -ZrB 2 composite ceramic coatings [5].…”

The in-situ growth of SiC whisker (SiCw) buffer layer on the surface of C/C composite material substrates provides an excellent solution to alleviate the thermal stress mismatch with the oxidation-resistant coating. Nevertheless, the growth mechanism of SiCw on the surface of C/C composite materials has been a subject of ongoing debate. This study initially investigates the reduction process of Ni(NO3)2·6H2O as a catalyst precursor and analyzes the morphological impact of Ni nanoparticles on the surface of C/C composite materials with respect to SiCw. Furthermore, it summarizes the V-L-S growth mechanism and V-S mechanism of SiCw, providing a comprehensive analysis of the microstructure and defects associated with SiCw growth under different mechanisms. The catalytic mechanism of Ni particles and the role of twinning and Z-shaped dipoles in whisker growth are elucidated. Finally, the influence of temperature and time on whisker morphology is examined, with particular emphasis on the occurrence of bead-like whiskers. This research extensively elucidates the growth process of SiCw on C/C composite substrate, resolving the previously ambiguous growth mechanism through structural analysis under diverse conditions.

In this study, SiC coating was prepared on carbon fibres from solution at ambient temperatures for the first time. The thickness of the coating was ∼85 nm. Analysis of the coatings revealed the presence of only SiC in the coating. The initial oxidation temperature of the SiC-coated carbon fibres increased by ∼50°C and the complete oxidation temperature was increased by ∼167°C, indicating excellent oxidation resistance owing to the presence of the SiC coating. We believe that the excellent properties and easy preparation process of SiC coating reported in this paper would provide us with a new way to produce SiC coating on carbon substrates.
