Thermal barrier coating (TBC) is being applied to blade and stator in a land-based gas turbine to protect these hot parts from a high-temperature gas environment. The interfacial cohesive strength of TBC coated components is diminished by a long-term experience under a high-temperature, because of forming a thermal oxidation at the coating interface or a microstructure in the ceramic coating layer being changed gradually. Consequently, it is quite important to understand how the interfacial strength of TBC changes with an exposed condition. This paper presents some experimental results for the interfacial fracture toughness of TBC coated material measured using the biaxial interfacial fracture test device developed by our group. A formation of the interfacial oxidation and an aspect of the interfacial fracture are related to change of the fracture toughness with an aging condition.
