Abstract
Interfacial behaviors of magnesia partially stabilized zirconia (MgO-PSZ) ceramic by nickel-based superalloy were investigated. And the effect of zirconia reduction on interfacial behaviors was considered. The contact angle became stable at 1390°C and was larger than 90° during the continuous temperature rise, and the equilibrium contact angle was 92°. The interfacial reaction between MgO-PSZ ceramic and nickel-based superalloy occurred at high temperature. The ZrO2 was reduced to suboxide (ZrO2−x), and the loss of oxygen led to the formation of Al2O3. The interfacial reaction was influenced by the reduction of ZrO2. The destabilization of MgO-PSZ ceramic was caused by the presence of Al2O3.
