摘要：

SiC ceramic has excellent overall properties, and joining it to other materials with high joint strength is an important issue in the actual applications. Brazing of SiC ceramic to itself was performed using the as-fabricated Al-(10, 20, 30, 40)Ti alloys with nominal Ti concentrations of 10%, 20%, 30%, and 40% at 1550 degrees C x 30 min. The average joint shear strength fluctuates in the range of similar to 100.260 MPa with the interlayer thickness of similar to 50 mu m. Moreover, the average strength SiC/Al-20Ti/SiC joint is increased markedly with the interlayer thickness decreasing from similar to 100 to 25 mu m, reaching the maximum of similar to 315 MPa. Meanwhile, the (Al) phase in the interlayers is reduced gradually till disappear with the thinnest brazing interlayer, leaving the Al4C3, TiC and (Al,Si)(3)Ti phases in the interlayer. The joint fractures of SiC/Al-20Ti/SiC joint mainly occur in the SiC ceramic substrate near the interlayer/ceramic interface.
