Tape Casting of Al ₂ O ₃ /ZrO ₂ Laminated Composites

Abstract

Fracture toughness of ZrO 2 ‐toughened alumina could he increased by macroscopic interfaces, such as those existing in laminated composites. In this work, tape casting was used to produce A/A or A/B laminates, where A and B can be Al 2 O 3 , Al 2 O 3 /5 vol% ZrO 2 , and Al 2 O 3 /l0 vol% ZrO 2 . An increase of toughness is observed, even in the Al 2 O 3 /Al 2 O 3 laminates.
