Abstract:	Turbine inlet temperature has been increasing for the demand of higher thermal efficiency of combined cycle gas turbines. Currently, MHI has been actively participated with Japanese national project which targets 62% combined cycle thermal efficiency through the development of 1,700 degC class gas turbine. Parts of the component technologies developed in the national project are applicable to 1,600 degC class gas turbine called M501J, which has the highest turbine inlet temperature in the world. In particular, thermal barrier coatings (TBCs) are one of the most essential technologies to achieve the target. During the development of advanced TBCs for new challenges, the pilot power plant called T-point in MHIs factory has been necessary. Advanced TBC coated on the actual hot parts can be verified in the plant and feedback can be obtained after operation. In this paper, TBC development and verification utilizing MHI's actual power plant are discussed.
