| 英文摘要 | An improved joining technique by reaction bonded technology was studied. The final densification and joining of the reaction-sintered composites were simultaneously completed in the reaction bonding process by one-step Si infiltration process. This method achieves joints with strong interfacial bonding and high flexural strength. The joint obtained by the one-step silicon infiltration reaction has a more uniform microstructure, the joint flexural strength is increased to 203 MPa, and retention rate of the flexural strength is 96%, which is comparable to the flexural strength of the C-f/SiC substrate. The microstructure and interfacial evolution mechanism of the interlayer were discussed. The results show that a transition layer of 2-3 mu m transition layer formed between the interlayer and the C-f/SiC substrate, which is composed of SiC crystal grains of about 0.5-1 mu m. The formation of the transition layer is due to the carbon concentration difference at the interface between interlayer and substrate, resulting in the diffusion of carbon during the Si-C reaction. |
