that the passive current density of Fe-based amorphous alloy is reduced by about one order of magnitude, and meanwhile, the stability of passive film can be guaranteed by the Cr/Mo molar ratio. The Mott–Schottky (M... of elements in the passive films. The results show that the corrosion resistance of the alloy is related to the molar ratio of Cr/Mo. The stability of passive film is determined by the synergistic......

that the oxidization kinetics of the alloy follows the parabolic rate law in the range of 600-800℃, the oxidization rate constant Kp increases as temperature elevating. The average oxidization rate at 800℃ for 200h is 0.00215mg·cm-2·h-1, showing the oxidization resistance of the alloy is the first grade. During oxidation, the oxidation film mainly consists of Cr2O3 and the growth of the oxidation film is mainly......
