Degradation of TBC Systems in Environments Relevant to Advanced Gas Turbines for IGCC Systems

Performer: University of Pittsburgh

Project No: FE0007271

Program Background and Project Benefits

This project will utilize high-temperature corrosion testing facilities to determine the degradation mechanisms of current state-of-the-art thermal barrier coating (TBC) in simulated syngas environments. Turbine materials research seeks to improve coating materials that will allow for higher temperature operation and increased durability leading to increased turbine efficiency and reduced maintenance. Specifically, this project will investigate how the interaction between the ash and oxidants affect TBC degradation through enhanced attack of yttria-stabilized zirconia (YSZ) top coating by chemical reaction, physical damage of the topcoat by molten deposit penetration, and accelerated bond coat corrosion.
