摘要
研究了不同编织方法的C/SiC复合材料与金属Nb的连接情况。采用液相渗透连接方法以Ni基连接剂为中间层在1300℃、保温时间45min、压力20MPa、真空条件下分别对二维、三维C/SiC复合材料与金属Nb进行了连接。结果表明二维C/SiC复合材料与金属Nb不能得到较好的连接,整个连接件在由连接温度降温到室温过程中已发生脱离现象;而三维C/SiC复合材料与Nb金属连接良好。
Liquid infiltration joining of C/SiC composite with various woven style and Nb was studied. The join procedure was carried out at the temperature of 1300°C with the holding time of 45 min in vacuum. The pressure applied was 20 MPa. Ni-base interlinker was employed as the interlayer. Results showed joints of laminated C/SiC composite and Nb had been disjoined during the joints were cooled from the joining temperature to room temperature. However favorable joints of 3D C/SiC composite and Nb could be gained.
