摘要：

The effect of 0, 1, 3 wt% Mo addition on the corrosion behavior of Fe21Cr5.5Al was studied through steam tests at 400 degrees C and 1200 degrees C. At 400 degrees C, Mo addition leads to non-protective Fe-Mo oxide growth on the surface, compromising protective uniform Cr oxide growth and subsequent Al2O3 layers as in the Mo-free specimen. At 1200 degrees C, the presence of Mo causes the spallation of the surface oxide scale. However, a thin alumina surface film was present. Current results show that Mo addition is detrimental to the corrosion resistance of FeCrAl alloy under both operational and accidental temperature scenarios.
