Evaluation of Microstructure and Bonding Strength on Interface of 3Y-TZP and Titanium

摘要

As part of the pressureless bonding of ceramics and metal, the bonding of 3Y-TZP and Ti using a bonding agent has been investigated. A zygote consisting of 3Y-TZP and Ti between, which the bonding agent was inserted, was heated at 1000℃ for 15 ～ 35min in an Ar flow (150mL/min). The agent is composed of a mixture of Cu_2O and activated carbon pasted with a small amount of ethy-lene glycol as binder, and specially the influence of C/Cu_2O molar ratio on the bonding strength of bonded bodies has been examined. The bonding strength of the zygotes was measured by four-point bending and tension tests. In the study, we confirmed by EPMA and XRD that the mechanical strength and microstructure in the interface of the bonded zygote are not only influenced by the carbon reduction of Cu_2O and but it is also decided by carburization of 3Y-TZP as well as heat treatment.
