Abstract

The use of the separated anode and cathode spaces during electrodeposition of the Fe–W alloy from a citrate bath (separation was carried out using a membrane with an average pore diameter of 0.74 μm) made it possible to significantly (up to 2 times) increase the current efficiency and deposition rate when using a graphite anode and to increase the performance electrolyte (constancy of surface composition and surface microhardness up to 4 A h l^–1). The dynamics of changes in the concentrations of the alloy-forming components of the electrolyte was studied and it was shown that it is defined not only by the electrodeposition of iron and tungsten into the alloy, but also by the absorption of tungstate by the anode.

使用分立式电解池对柠檬酸浴中的Fe-W涂层进行电沉积

摘要

在从柠檬酸盐浴中电沉积Fe–W合金期间使用分开的阳极空间和阴极空间（使用平均孔径为0.74μm的膜进行分离）可以显着增加（最多2倍）使用石墨阳极并提高电解质性能时的电流效率和沉积速率（表面成分的恒定性和表面显微硬度最高4 A hl ^–1）。研究了电解液中合金成分的浓度变化的动力学，结果表明，它不仅由铁和钨在合金中的电沉积所决定，而且还受阳极对钨酸的吸收所决定。
