The research and development of more efficient gas turbines has been one of the central focuses in materials design and characterisation for the past 20 years. High-temperature materials capable of maintaining their properties at elevated temperatures and under load are required for a wide range of components such as aircraft gas turbine engines, steam turbines, and industrial gas turbines. The operating temperature for gas turbine blades used for aerospace, marine and power plant applications, has been continuously increased in order to improve fuel efficiency. Nickel-based superalloys with various types of high temperature coatings have been widely and successfully used for such applications. [Continues.]
