Project Description

The Oak Ridge National Laboratory (ORNL), with support from Stony Brook University, will develop and evaluate approaches for improved alloys and coatings to provide the basis for more robust thermal barrier coating (TBC) materials systems needed for higher-efficiency land-based gas turbines, especially those fired with coal-derived syngas and hydrogen-enriched fuels. The project focuses on the high-temperature performance and advanced characterization of relevant metallic bond coatings and conventional and state-of-the-art multifunctional ceramic top coatings for TBC systems. This project benefited from work conducted under the prior DOE contract FWP-FEAA070.

Project Benefits

The ORNL research is aimed at the deployment of the optimal technology (i.e., a more durable TBC with potentially higher surface temperatures and/or longer component lifetime) available through multilayer coating design (both metallic bond coating and ceramic top coating). It includes advanced fabrication, characterizing and testing specimens of increasing complexity (to better replicate application conditions and enable more sophisticated evaluations, e.g., in burner rig testing) and engagement of industrial partners to further evaluate the TBC systems showing the greatest promise on the basis of the laboratory work.
