Extremely strong diffusion bonds can be made directly between Y 2 O 3 ‐stabilized TZP ZrO 2 and Fe─18Cr─8Ni stainless steel above a critical joining temperature of about 1100°C. Fracture initiates at the metal/ceramic interface with plasticity occurring in the metal. Bonding is accompanied by a thin interfacial reaction layer which may possibly lead to local melting during the bonding cycle. This behavior is similar to that observed with Ni─Cr alloys bonded to TZP ZrO 2 , but a less vigorous interfacial reaction occurs with stainless steel, and stronger bonds can be made.
