Abstract

Aluminum-doped lanthanum strontium manganese oxide, La0.77Sr0.20Al0.9Mn0.1O3 (LSAM), was joined to stabilized tetragonal zirconia polymorph YTZP (ZrO2)0.97(Y2O3)0.03 by a uniaxial stress (3–6 MPa) and high-temperature (1250–1350 °C) bonding method that initiates grain-boundary sliding between the ceramic components. The flow stress of LSAM was larger than that of La0.8Sr0.2Mn0.3 under the same test conditions. Electron microscopy confirmed that intergranular penetration occurred at the joining plane, leading to effective bonding between the two dissimilar ceramics. Raman spectral maps of the joining planes obtained with 2-D Raman microscopy demonstrated the absence of any new phases at the interface.
