摘要：

In this work, micro/nano size pits were introduced to the surface of Fe80B20 amorphous ribbons by electro-chemical etching treatment. The results show that the size of the pits is more sensitive to the applied etching potential, while the pit homogeneity is time dependent. The etching treatment at - 0.30 V (vs saturated calomel electrode) for three hours in 1 M HCl solution saturated by KCl leads to the formation of numerous pits with an average diameter of 222 nm. The large amount of pits results in higher degradation efficiency on Direct Blue 15 when compared with the as-spun amorphous alloy.
