In this work, solid-phase hydrogen diffusion is investigated as a treatment for a Co-based (Co_75.4Fe_3.5Cr_3.3Si_17.8) amorphous membrane, made of metallic glass. We report a noticeable growth of diffusion through the amorphous membrane at higher environmental acidity and constant ionic activity in the chloride-acidic solutions. This effect has been explained by a presence of two adsorpted hydrogen atomic forms (superficial and subsurface ones) on the specimen surface during the chemical treatment. Mentioned impact provides explicit changing by magnetic and mechanical properties of the alloy, and it is compared and approved using literature data. A scheme of the process has been proposed and verified with X-ray photoelectron spectroscopy and magnetometry. Presented results can be interesting both from fundamental and practical standpoints in material science and technology of amorphous alloys.

通过固相氢扩散对 Co 基非晶膜物理力学性能的影响


在这项工作中，研究了固相氢扩散作为金属玻璃制成的钴基 （Co_75.4Fe_3.5Cr_3.3Si_17.8） 非晶膜的处理。我们报告了在较高的环境酸度和氯酸性溶液中的恒定离子活性下，通过无定形膜的扩散明显增加。这种效应可以通过在化学处理过程中样品表面存在两种吸附的氢原子形式（表面和次表面形式）来解释。上述影响通过合金的磁性和机械性能提供了明确的变化，并使用文献数据对其进行了比较和批准。已经提出了该过程的方案，并用 X 射线光电子能谱和磁力计进行了验证。从非晶合金材料科学和技术的基础和实践角度来看，所呈现的结果都可能很有趣。
