Development of Advanced Low Conductivity Thermal Barrier Coatings by National Aeronautics and Space Administration (NASA) Pdf

Advanced multi-component, low conductivity oxide thermal barrier coatings have been developed using an approach that emphasizes real-time monitoring of thermal conductivity under conditions that are engine-like in terms of temperatures and heat fluxes. This is in contrast to the traditional approach where coatings are initially optimized in terms of furnace and burner rig durability with subsequent measurement in the as-processed or furnace-sintered condition. The present work establishes a laser high-heat-flux test as the basis for evaluating advanced plasma-sprayed and electron beam-physical vapor deposited (EB-PVD) thermal barrier coatings under the NASA Ultra-Efficient Engine Technology (UEET) Program. The candidate coating materials for this program are novel thermal barrier coatings that are found to have significantly reduced thermal conductivities and improved thermal stability due to an oxide-defect-cluster design. Critical issues for designing advanced low conductivity coatings with improved coating durability are also discussed. Zhu, Dong-Ming and Miller, Robert A.

Low Conductivity Thermal Barrier Coatings by National Aeronautics and Space Administration (NASA) Pdf

Thermal barrier coatings will be more aggressively designed to protect gas turbine engine hot-section components in order to meet future engine higher fuel efficiency and lower emission goals. In this presentation, thermal barrier coating development considerations and requirements will be discussed. An experimental approach is established to monitor in real time the thermal conductivity of the coating systems subjected to high-heat-flux, steady-state and cyclic temperature gradients. Advanced low conductivity thermal barrier coatings have also been developed using a multi-component defect clustering approach, and shown to have improved thermal stability. The durability and erosion resistance of low conductivity thermal barrier coatings have been improved utilizing advanced coating architecture design, composition optimization, in conjunction with more sophisticated modeling and design tools.Zhu, Dong-MingGlenn Research CenterTHERMAL CONTROL COATINGS; THERMAL CONDUCTIVITY; CORROSION RESISTANCE; DESIGN OPTIMIZATION; THERMAL STABILITY; TEMPERATURE GRADIENTS

Thermal and Environmental Barrier Coatings for Advanced Turbine Engine Applications by National Aeronautics and Space Administration (NASA) Pdf

Ceramic thermal and environmental barrier coatings (T/EBCs) will play a crucial role in advanced gas turbine engine systems because of their ability to significantly increase engine operating temperatures and reduce cooling requirements, thus help achieve engine low emission and high efficiency goals. Advanced T/EBCs are being developed for the low emission SiC/SiC ceramic matrix composite (CMC) combustor applications by extending the CMC liner and vane temperature capability to 1650 C (3000 F) in oxidizing and water vapor containing combustion environments. Low conductivity thermal barrier coatings (TBCs) are also being developed for metallic turbine airfoil and combustor applications, providing the component temperature capability up to 1650 C (3000 F). In this paper, ceramic coating development considerations and requirements for both the ceramic and metallic components will be described for engine high temperature and high-heat-flux applications. The underlying coating failure mechanisms and life prediction approaches will be discussed based on the simulated engine tests and fracture mechanics modeling results.Zhu, Dong-Ming and Miller, Robert A.Glenn Research CenterTHERMAL CONTROL COATINGS; GAS TURBINE ENGINES; CERAMIC COATINGS; CERAMIC MATRIX COMPOSITES; COMBUSTION CHAMBERS; ENGINE PARTS; CERAMICS; AIRFOILS; REFRACTORY MATERIALS; THERMAL CONDUCTIVITY; METALS; SILICON CARBIDES
