## 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
In order to understand the degradation of thermal barrier coating (TBC) systems better, we determined the adhesion energy (G c ) between the bond coat and the top coat and its evolution during cyclic oxidation. This energy was evaluated by means of a modified four-point bending test. The systems tes
