Oxidation resistance and thermal cycling properties of the SiCnws–SiC coating on the C/SiC composites

Abstract
Abstract SiC coatings reinforced with SiC nanowires were prepared on carbon/silicon carbide (C/SiC) composites through chemical vapor reaction route and chemical vapor deposition (CVD). The SiC nanowires were introduced to mainly improve the interface bonding properties of the coating and C/SiC composites. The microstructure, phase composition, thermal cycling, and bonding strength of the SiCnws–SiC coating were investigated. After nine thermal cycles, the weight loss of the SiCnws–SiC‐coated C/SiC composites was only 4.6 wt.%. Tensile test results show that the tensile strength of the SiCnws–SiC‐coated C/SiC composites was more than 4.5–4.6 MPa. The introduction of SiC nanowires effectively improved interface bonding strength, thus enhancing the thermal cycling and mechanical properties of the coating.
