Symposium Sandphobic Thermal/Environmental Barrier Coatings
Presentation Title Multiphase Thermal Barrier Coatings for Broad-base Resistance to Silicate Deposits
Author(s) David Poerschke
On-Site Speaker (Planned) David Poerschke
Abstract Scope The need to overcome degradation caused by molten silicate debris and deposits has emerged as a primary design requirement for future generations of thermal and environmental barrier coatings (T/EBC), which protect structural components in the hot sections of gas turbine engines. The challenge is magnified by the broad range of potential debris compositions, which make it unlikely that any single coating material will provide the desired performance in all environments. Instead, multiphase coatings are needed. Recent efforts have focused on understanding the thermochemistry of the coating-deposit interactions over a wider range of coating and deposit compositions to develop computational design tools capable of rapidly screening a variety of coating compositions. This accelerated approach was used to identify the most promising candidates involving two- and three-phase combinations of rare earth zirconates and aluminates. The results point toward promising new opportunities to design high-performance TBC systems.
