Summary

Thermal barrier coating (TBC) is effective in order to reduce metal surface temperature of turbine components and achieve higher temperature of turbine inlet temperature. However, TBC on the turbine blade fractures by the accumulated damage as the increase of thermal cycles. Thus, the durability estimation of TBC is needed before it is applied to engine parts. in this study, the location and the fracture mode of thermal cycle damage of TBC system sprayed on a plate was investigated from the observations after thermal cycle test and the calculations by finite element method (FEM). Burner rig test was carried out to examine the characteristics of thermal cycle damage of TBC in air. Two kinds of TBC systems were used for the test. Those microstructures before and after the tests were observed by optical microscope. The stresses and strains were also calculated by FEM when thermal loadings of one cycle were given to the specimen.
