SAMBA: Self-Healing Thermal Barrier Coatings for Prolonged Lifetime



The SAMBA project is funded by the European Union under its 7th Framework Programme (NMP theme) with project number 309849. The project started on 1 March with a duration of 4 years. The consortium to carry out this project consists of leading European academic and industrial parties in the field of thermal barrier coating design, manufacturing, characterization and lifetime assessment as well as end-users.



The SAMBA project deals with the creation of a new, unique self-healing thermal barrier coating (TBC) for turbines and other thermally loaded structures in order to realize a significant extension of the lifetime of critical high-temperature components. The concept is based on novel Al2O3 coated Mo-Si particles embedded in the TBC layer, typically consisting of yttria-stabilized zirconia. As the current TBCs do not exhibit any self-repair, the new self-healing TBC will offer a reduction of the number of TBC replacements during an engine lifetime and enhance the reliability of the critical components.



The project deals with six interrelated RTD work packages.

  • WP2 pertains to the concept and design of a self-healing TBC
  • WP3 is focused on the manufacturing of the TBC systems
  • WP4 is dedicated to the assessment of the TBC lifetime improvement and associated failure analysis
  • WP5 concerns the characterization of the microstructure and properties including damage and healing assessment
  • WP6 is focused on bringing the concept into practice with a rig demonstration
  • WP7 addresses the dissemination and exploitation of all results of this project.


WP1 and WP8 deal with consortium coordination and project management.
