Area of Research: Materials

Federal Project Manager: Briggs White

Project Objective: This project is focused on developing novel coatings for high-H2 fired gas turbine components such that high efficiencies and long lifetimes may be acheived in Integrated Gasification Combined Cycle (IGCC) powerplants. Nanostructured Hafnia-based coatings will be develped for thermal barrier coatings (TBCs). A fundamental understanding of TBCs will be aquired and a knowledge database of next generation TBC materials with high-temperature tolerance, durability, and reliability will be generated. TBCs will be delivered which meet the DOE required performance target of reliable surface temperature tolerance greater than 1300C for a minimum of 8,000 hours. The delivered TBCs will have superior heat resistance, thermal insulation, oxygen barrier qualities, hot-corrosion and erosion resistance, and resistance to adverse coating/substrate interactions.
