Al{sub 2}O{sub 3}/Y{sub 2}O{sub 3}-stabilized ZrO{sub 2} (YSZ) and La{sub 0.85}Sr{sub 0.15}MnO{sub 3} ceramics were joined by plastic deformation at 1200--1350 {sup o}C. Pieces were joined directly to each other or with an interlayer. For some of the Al{sub 2}O{sub 3}/YSZ specimens, the interlayer was applied by spraying of powders entrained in an organic vehicle. All final joints were as dense as the host ceramics and generally featured finer grain sizes. When dissimilar compositions were joined, thermal residual stresses were generated. Choice of composition could tailor these stresses and produce joints that were as strong as the surrounding ceramics. Strength of the Al{sub 2}O{sub 3}/YSZ joints and the electrical resistivity of a joint in La{sub 0.85}Sr{sub 0.15}MnO{sub 3} were as good as those of the host ceramics.
