Amélioration du comportement en cyclage thermique d'un dépôt plasma métallique par compression isostatique à chaud.
Résumé
A HIP post-treatment applied on LLPS FeCrAlY coatings improved resistance under thermal cycling (high coating densification, strong adherence to substrate). Observation of the oxide scale using SEM, enabled us to explain such an improvement of the behaviour of post-hipped coatings when submitted to both oxidation and thermal stresses.
