Thermal Barrier Coating Environmental Durability Enhancement (CMAS)

Advanced thermal barrier coating systems are desired for naval gas turbine engines. These coatings will increase the durability of hot-section engine components to significantly improve the time "on-wing", safety and readiness of these engines. In this work, we will use novel coating synthesis techniques that enable the deposition of advanced compositions and microstructures to achieve a comprehensive thermal barrier coating system that provides vastly improved resistance to damage from CMAS. A low cost, high throughput processing approach for the application of this TBC system is also envisioned. The proposed Phase II effort will optimize CMAS protection concepts that are anticipated to meet the performance goals at both current and future engine operating temperatures and demonstrate the ability to apply these concepts onto engine components using production scale processing techniques. The successful completion of the work will result in coatings that meet the requirements for entrance into a qualification engine test for use on Navy and other DOD engines. Success in these objectives will offer the military a pathway toward production implementation of these advanced coatings and the new deposition processing capabilities required for applying coatings of this type onto engine components.
