10 Years-Activities at ONERA on Advanced Thermal Barrier Coatings

Résumé

Developing thermal barrier coatings operating at higher temperature and/or for very long durations (commercial aircraft applications) is one of the technological and economical challenges for engine manufacturers. This includes the search for (i) low thermal conductivity, high thermal stability and CMAS resistant ceramic top coat, and (ii) alternative low cost bond coat with improved oxidation resistance and chemical compatibility with the substrate. This paper reviews the rationale sustaining the choice of new materials for each layer and presents some recommendations to develop more robust and more efficient systems with increased lifetime.
