Alumina/Alumina and Alumina‐Zirconia/Alumina‐Zirconia Joints Through Glass Interlayers, Microstructure, Mechanical Properties and Residual Stresses

As alternative to traditional joining methods, Ca‐Al silicate glasses were used to self‐bond alumina and alumina‐zirconia ceramics under different processing conditions. Microstructures, mechanical properties and residual stress studies have shown glassy interlayer characteristics to be correlated with the chemistry of the starting glasses and of the ceramics.
