Hydration Tolerant, low Thermal Conductivity (K) Thermal Barrier Coatings

Phase 2 SBIR

Agency: Air Force
Topic: AF121-175
Budget: 01/01/14 - 12/31/14
PI: Dr. Derek D. Hass

ABSTRACT: Thermal barrier coatings (TBC) are currently employed to protect gas turbine engine components. Thermally exposed TBC systems have been observed to be affected by moisture. This spallation mechanism, Moisture Induced Delayed Spallation (MIDS), occurs at room temperature while the coatings are not exposed to the thermal-mechanical inpu...

Optimizing Coating Processes and Chemistries for Enhanced Hot Section, Low Cycle Fatigue (LCF) Life

Phase 2 SBIR

Agency: Air Force
Topic: AF121-171
Budget: 12/30/13 - 04/04/16
PI: Susie Eustis

ABSTRACT: Environmental protection coatings are required to provide oxidation and hot corrosion protection to hot section turbine components. Unfortunately, the current generation of such coatings can degrade the fatigue resistance of the coated alloy. It is increasingly recognized that, due to the detrimental effect of the coating on low cycle...

Advanced Deposition Capability for Oxidation&Corrosion Protection Coatings

Phase 1 STTR

Institution: University of Pittsburgh

Agency: National Aeronautics and Space Administration
Topic: 12-1-T12.01
Budget: 01/01/13 - 12/31/13
PI: Susie Eustis

NASA's long range goals of reducing the fuel consumption by 30% and increasing fuel efficiency by 35% can be partially accomplished through increasing engine operation temperatures. As a result, the disk section is desired to operate in increasingly higher temperatures, which will subject it to additional degradation mechanisms of oxidation and...
