非晶结构对腐蚀的影响是一个长期困扰人们的问题。为了阐明这种关系，选择了Zr2Ni金属玻璃及其单晶对应物，其中它们在组成和结构上都是均匀的。在0.1M NaCl水溶液中的腐蚀行为进行了评价。与单晶相比，非晶合金具有更高的耐蚀性。非晶合金表面钝化膜中ZrO 2含量较高，NiO含量较低。这些结果表明，非晶态结构可以有效地影响钝化膜的组成和可镀性。
The effect of amorphous structure on corrosion is a long-term puzzling problem. To elucidate this relationship, a Zr2Ni metallic glass and its single crystal counterpart were selected, in which they are both homogeneous in composition and structure. The corrosion behaviour has been evaluated in 0.1M NaCl aqueous solution. Compared with the single crystal, the amorphous alloy presents a higher corrosion resistance. The passive film formed on the amorphous alloy contains more ZrO2and less NiO content. These results reflect that the amorphous structure could effectively influence the composition and compactability of passive films.
