Oxidation‐induced crack healing and erosion life assessment of Ni–Mo–Al–Cr7C3–Al2O3 composite coating

The present investigation focuses on the effect of Cr2AlC MAX phase addition on erosion and oxidation‐induced crack healing behavior of Ni–Mo–Al alloy. For this, Ni–Mo–Al and 20 wt% Cr2AlC‐blended Ni–Mo–Al powders were coated by Air Plasma Spray (APS). For oxidation‐induced crack healing studies, th...
