Functionally Graded Materials designed for thrusters : resistance under laser thermal flux and in combustion environment

Résumé

Functionally Graded Materials (FGM) are developed by ONERA, CNES and ICB to withstand harsh thermal and environmental conditions induced by new green propellants in satellite thrusters. In this study, different types of FGM are elaborated through Atmospheric Plasma Spraying (APS) and tested in representative environments to assess the influence of the FGM composition profile. In particular, the resistance of FGM facing thermal shock tests is evaluated with a laser test bench, and its resistance in oxidative flow in a combustion chamber with a H2/O2 flame. FGM with thin ceramic layer exhibit very good behavior under these conditions.
