The influence of surface roughness on joining of alumina (Al_2O_3) to itself and that of silicon nitride (Si_3N_4) to itself utilizing superplastic ceramics as interlayer was studied. The surface roughness on joining of ceramics was used as a variable for the bonding experiments, and the examination on bonded conditions by means of SEM was carried out. In the case of joining of alumina to itself, when maximum surface roughness was larger than 2.13μm, the bonded specimen showed a good bonding microstructure. In the case of joining of silicon nitride to itself, the bending strength was not influenced by surface roughness.
