High temperature (HT) coatings are applied on hot-section components of gas turbines to prevent them from premature failure caused by oxidation, hot corrosion, and overheating. As the turbine firing temperature continually increases in the recent years with the introduction of more advanced turbine designs, the hot-section components in these turbines are running at increasingly high temperatures, and HT coatings applied on these hot-section components need provide better protection in order to meet the designed performance criteria. Phase I of this project will identify HT coating performance requirements and specifications for the F402 and T700 naval aircraft engines, define application techniques and characterize the coating systems composition, and select one or more coatings for further development in Phase II. Phase II will conduct laboratory hot gas and cascade tests of selected coating systems, and Phase III will carry out the accelerated simulated mission endurance test to determine the coating system performance in an integrated engine under realistic operational conditions. The optional portion of this project will also include selecting HT coatings for the advanced F414 and F119/F120 engines with higher turbine firing temperatures
