Thermal barrier coatings (TBC`s) have been used in high thrust aircraft engines for many years, and have proved to be very effective in providing thermal protection and increasing engine efficiencies. TBC life requirements for aircraft engines are typically less than those required for industrial gas turbines. This paper describes current and future applications of TBC`s in industrial gas turbine engines. Early testing and applications of TBC`s is reviewed. Areas of concern from the engine designer`s and materials engineer`s perspective are identified and evaluated. This paper focuses on the key factors that are expected to influence utilization of TBC`s in advanced industrial gas turbine engines. It is anticipated that reliable, durable and highly effective coating systems will be produced that will ultimately improve engine efficiency and performance.
