Résumé

Characterization of the microstructure of thermal barrier coatings (TBCs) is essential for assessing coating lifetime and for understanding the damage mechanisms leading to ceramic layer spallation. Recent progress in synchrotron-radiation computed laminography (SRCL) enables imaging of samples that are thin but extended in two dimensions. This study reports on the first results of the 3-D characterization of electron beam-physical vapour deposition TBCs by SRCL. Image analysis was very helpful in investigating the 3-D microstructure obtained and is also described.
