摘要：
Developing amorphous alloys with good corrosion resistance has attracted wide interests recently. In this work, a series of Fe73.5-xNixCu1Nb3Si13.5B9 (x = 0, 1, 2, 3 and 4 at.%) amorphous alloys are fabricated. The influence of Ni addition on the structure and corrosion resistance of the alloys in KNO3 solution was investigated. The amorphous ribbons showed excellent corrosion resistance due to the formation of a stable passive film that ensured a very large passivation plateau. The corrosion resistance is sensitive to the minor addition of Ni (<= 4 at.%), which significantly improved the corrosion resistance according to the results of electrochemical measurements.
