摘要：

SiC coatings were prepared on carbon/carbon (C/C) composites by chemical vapor reaction (CVR) method. The structure and morphology of the coating were characterized by XRD, SEM and EDS analysis, and the influence of SiC coating and preparation technology on the fracture behavior of the composites were investigated by three point bending tests. The results show that the flexural strength and maximum fracture displacement of the composites are obvious improved after the coating process. The average flexural strength of carbon/carbon composites is 172.4MPa, while the average flexural strength of the coated composites is 239.8MPa. The improvement of the flexural strength is mainly contributed to the improved interface bonding caused by the vapor diffusion and reaction in the preparation process and the SiC particle reinforcement. Furthermore, the fracture mode of the coated composites is not changed and the coated samples also exhibit pseudo-plastic fracture and ductile fracture character.
