During high-temperature exposure, the microstructure of thermal barrier coatings evolves, leading to increased thermal conductivity. We describe the evolution in the thermal properties of a 7 wt.% Y 2 O 3 stabilized ZrO 2 electron beam-physical vapor deposited (EB-PVD) thermal barrier coating with t

## Abstract The thermal conductivity of electronβbeam physical vapor deposited (EBβPVD) thermal barrier coatings (TBCs) was investigated by the Laser Flash technique. Sample type and methodology of data analyses as well as atmosphere during the measurement have some influence on the data. A large v
Thermal barrier coatings (TBCs) are being developed for the key technology of gas turbine and diesel engine applications. In general, 8 mass% Y 2 O 3 -ZrO 2 (8YSZ) coating materials are used as the top coating of TBCs. The development of hafnia-based TBC was started in order to realize the high reli
