The gas turbine doubtlessly is one of the most important modern machines to convert energy from heat to power, and improving its efficiency is a ceaseless task. The most practical route to increase the efficiency is to increase the maximum operating temperature. Over the past several decades, the improvement of this temperature was constantly attained by the developments of thermal barrier coating and superalloys, but almost reached a limit because the microstructural deterioration of both the base superalloy and the coating system due to the interdiffusion between them can be dramatically...
