摘要

A SiO₂-Nd₂O₃/Si-SiC-MoSi₂ coating was proposed to repair the damaged SiC coated C/C composites by laser cladding. Laser ablation was performed to evaluate the effect of coating repair. Results showed that the preparation of the SiO₂-Nd₂O₃ outer layer could improve the laser ablation resistance of the specimens by weakening heat accumulation and enhancing heat consumption, which reduced the maximum temperature by 261.99 K and 694.75 K during ablation under 300 W and 500 W for 7 s. The growth of the ablative products, including the Si nanowires and SiO_x spherical particles, was based on vapor deposition and oxide-assisted growth mechanism.
