New test equipment for high temperature materials of gas turbine has been developed. The equipment can give mechanical loading on the test sample in combustion environment by combination of an advanced combustor system and a servo hydraulic material testing system. In this study, by using of the apparatus, thermal barrier coated specimen tested under the condition of the cyclic burner heating together with constant tensile loading. After the testing, cracks of the coating were observed. Those cracks grew and increased with the number of the testing cycle. Degree of the coating damages indicated the dependence on the temperature distribution of specimens in the high temperature gas flow filed. The testing system has possibility of success to evaluate the damage of the thermal barrier coating system at closer condition with actual engine operation.
