Project Description

With engine temperatures exceeding the limits that metallic blades and vanes can endure, advanced monitoring techniques that ensure the integrity and durability of thermal barrier coatings are paramount to continuous and safe operation. The University of Central Florida will use key properties of optical radiation—including temporal, spectral and spectral intensity response modes, coupled with active sensing from coating properties—to gain diagnostic information on high temperature Thermal Barrier Coatings (TBCs). Materials design incorporating rare earth elements within TBCs to create the self-indicating property will be accompanied by research efforts to correlate optical measurements to TBC diagnostic parameters. The methods will be developed and demonstrated at the laboratory scale with the goal of future implementation for gas-turbine ready conditions.

Project Benefits

Anticipated benefits from projects funded through the University Turbine Systems Research (UTSR) Program include development of technologies that will accelerate turbine performance, efficiency, and emissions reduction beyond the current-state-of-the-art and reduce the risk to market for novel and advanced turbine-based power generation. In addition, the UTSR Program seeks to maintain and enhance U.S. university-based turbine science capabilities to ensure a world-class scientific workforce for future generations. UTSR is a component of NETL’s Advanced Turbines Program that manages a portfolio of projects designed to remove environmental concerns over the future use of fossil fuels by developing revolutionary, near-zero-emission advanced turbines technologies.
