Peer-Reviewed Section


Carbon fibre-reinforced silicon carbide matrix composite (Cf/SiC composite) is a new heat-resistant ceramic matrix composite, and it shows a high potential for applications in high temperature environments. However, reliable joining technology is still lacking for this material. In the present paper, the contact angles of Pd-Co-V system alloys on Cf/SiC composite were measured using the sessile drop method. On this basis, one kind of Pd-Co-V alloy, in the powder form of the mixture of elemental components was used as brazing filler metal, and Cf/SiC composite joints were achieved after brazing at 1 523 K for 20 min. The microstructure of the Cf/SiC composite joints was examined with SEM and XEDS. It was found that elements Pd and V in the filler metal participated in the interfacial reactions between the composite and the brazing filler metal. The reaction products were analysed, and the joining mechanism was discussed.
