Nano-infiltration and transient eutectic (NITE) phase joining SiC ceramics at 1500oC

Abstract
Abstract By using nano-infiltration and transient eutectic (NITE) phase with nanosized SiC and the addition of CeO2–Al2O3 as joining material, liquid-phase-sintered SiC ceramics were joined at the relatively low temperature of 1500 °C and 1700 °C. For comparison purpose, Al2O3–Y2O3 and SiO2–Al2O3–Y2O3 were used as the additives to join SiC ceramics. The shear strength of SiC assembly with the interlayer thickness of ~70 μm and addition of CeO2–Al2O3 after joining at 1700 °C was measured to be 163.9 MPa but decreased to 57.4 MPa when joining at 1500 °C. It was revealed that the joining status could be improved by decreasing the thickness of the interlayer to ~35 μm and SiC joint finishing at 1500 °C possessed the comparatively high shear strength of 113.2 MPa. NITE phase containing other additives (Al2O3–Y2O3 and SiO2–Al2O3–Y2O3) showed the much lower shear strength after joining at 1500 °C.
