We study the electrochemical behavior of Fe80Si6B14, Co72Si18B10, and Fe84Nb2B14 amorphous metal alloys based on Fe and Сo in alkali solutions of different concentrations. The protective oxide layers on Fe80Si6B14 electrodes have lower degrees of corrosion protection than for the Co72Si18B10 electrodes. Niobium clusters in the Fe84Nb2B14 alloy are reactive, which results in the rapid initial interaction of the electrode with a 1 М aqueous solution of KОН, which is retarded under the conditions of long-term contact with ions of the electrolyte. The Fe80Si6B14 and Fe84Nb2B14 alloys are characterized by a similar electrochemical behavior in 1 M and 5 М aqueous solution of KOH under the conditions of cyclic polarization of samples in corrosive media. As a result of fivefold scanning of the potential, it is shown that the electrochemical properties of the electrodes made of amorphous metallic alloys depend on the electrolyte concentration.

铁钴基三元非晶合金在碱溶液中的电化学性能

我们研究了基于 Fe 和 Сo 的 Fe80Si6B14、Co72Si18B10 和 Fe84Nb2B14 非晶金属合金在不同浓度的碱溶液中的电化学行为。Fe80Si6B14 电极上的保护性氧化层的腐蚀保护程度低于 Co72Si18B10 电极。Fe84Nb2B14 合金中的铌簇是反应性的，这导致电极与 1 М KОН 水溶液的快速初始相互作用，在与电解质离子长期接触的条件下被延迟。Fe80Si6B14 和 Fe84Nb2B14 合金的特点是在腐蚀介质中样品循环极化的条件下，在 1 M 和 5 М KOH 水溶液中具有相似的电化学行为。由于对电位进行了五重扫描，
