Influence of the coating brittleness on the thermomechanical fatigue behavior of a $\beta$-NiAl coated R125 Ni-based superalloy

Capucine Billard, Damien Texier, Matthieu Rambaudon +6

The brittleness of an aluminide diffusion coating protecting a René 125 Ni-based polycrystalline superalloy was investigated over a wide range of temperatures in its as-received an…
