Oxide Scale Stress Determination by Raman Spectroscopy Application to the NiCr/Cr2O3 System and Influence of Yttrium
Résumé
The performance of nickel-based alloys as heat resistant materials is strongly dependant on their oxidation resistance. A strong resistance to oxidation of Ni-Cr alloys is expected due to the formation of a protective Cr2O3 layer which blocks the diffusion of nickel ions to the oxide scale/gas interface and prevents from fast growth of a NiO scale.
