In this work, an attempt was made to reveal and explain the influence of the process of formation of 2D nanostructures at the surface of an amorphous alloy (an alloy with the composition Co75Si15Fe5Cr4.5Al0.5 (in at.%) was used for this purpose) on the corrosion and magnetic properties of such an alloy. Two-dimensional nanostructures (nanocells of 100-150 nm in size, which were obtained by anodizing the initial sample in an ionic liquid) are essentially a pattern on the surface of the sample, and they cannot completely cover and block the surface from external effects. It was postulated that the presence of these nanostructures during corrosion and magnetic tests has no significant effect. However, a noticeable inhibition effect was observed during corrosion tests and a less noticeable (but still detectable) effect was observed during magnetic tests. The authors believe that the effect obtained, with a detailed study, can be used to increase the corrosion resistance and to improve the properties of traditional magnetic materials.
在这项工作中，试图揭示和解释非晶合金表面 2D 纳米结构形成过程（为此目的使用组成 Co75Si15Fe5Cr4.5Al0.5（按原子%计）的合金）对这种合金的腐蚀和磁性的影响。二维纳米结构（大小为 100-150nm 的纳米细胞，通过在离子液体中对初始样品进行阳极氧化获得）本质上是样品表面的一种图案，它们不能完全覆盖和阻挡表面免受外部影响。据推测，在腐蚀和磁性测试过程中，这些纳米结构的存在没有显著影响。然而，在腐蚀测试中观察到了明显的抑制作用，在磁性测试中观察到了不太明显（但仍然可以检测到）的作用。作者认为，通过详细研究获得的这种效果可用于提高耐腐蚀性并改善传统磁性材料的性能。
