  Effects of reaction layer and brazing temperature on the shear strength of high chromium white cast irons/Al<sub>2</sub>O<sub>3</sub>, Si<sub>3</sub>N<sub>4</sub>, SiC joints are studied using active filler metal and aluminum. The microstructures and reaction layer in the joints are investigated by scanning electron microscopy and X-ray diffraction. Shear strength of about 180-200 MPa was obtained at high chromium cast irons-Al<sub>2</sub>O<sub>3</sub> and Si<sub>3</sub>N<sub>4</sub> joints brazed at 1123-1173K for 15 min, though the shear strength decreased to 150-160 MPa at 1073K for 15 min. In the case of high chromium white cast irons-SiC joint brazed at 1173-1373K for 5 min, shear strength of about 30-50 MPa. was obtained. Reaction products TiO or TiN were formed in the interface between active filler metal and Al<sub>2</sub>O<sub>3</sub>, Si<sub>3</sub>N<sub>4</sub>, two compounds (Al<sub>3</sub>Fe, Al<sub>4</sub>C<sub>3</sub>) were formed in the high chromium cast irons-SiC joint brazed with aluminum filler metal. These reaction layer should influence the shear strength of high chromium cast irons-ceramic joints.
