Influence of the Architecture on the Mechanical Performances of Alumina-Zirconia-Mullite Ceramic Laminates

Abstract:

Ceramic laminates with different architecture have been produced and characterized in this work. Thickness of single layers, composition and stacking sequence have been changed in order to modify the corresponding stable growth range of surface defects and final strength. Laminates composed of alumina/zirconia and alumina/mullite have been considered. The mechanical behaviour of the materials is discussed in terms of the residual stress profile and the apparent fracture toughness curve.
