Abstract
This paper describes a process of electrolytic deposition of Ni-Co binary alloy on Fe powder. Electrochemical behavior of this binary alloy was studied by cyclic voltammetry (CV) with a paraffin impregnated graphite electrode (PIGE) as a working electrode. Deposition of individual metals (Ni, Co), as well as the simultaneous nickel-cobalt co-deposition, was performed in aqueous solutions (Watts-type electrolyte) both with and without Fe powder. Special attention was paid to the influence of suspension density on the electrode process. This density affects on the quality of iron powder electroplating. Preferential deposition of the less noble metal (Co) leading to its higher content in the deposit was observed in contrast to the more noble one (Ni) in spite of higher content of Ni in the plating solution. Understanding the anomalous behavior would lead to better control of the deposition process and to explanation of the mechanism of Ni-Co co-deposition.
Abstract (in Czech)
Práce popisuje proces elektrolytické depozice Ni-Co binární slitiny na železném prášku. Elektrochemické chování této slitiny bylo studováno pomocí cyklické voltametrie na parafinem impregnované grafitové elektrodě. Speciální pozornost byla věnnována vlivu suspenzní hustoty Fe prášku na elektrodový proces.Preferenční depozice méně ušlechtilého kovu (Co), směřující k vyššímu obsahu depositu, byla pozorována i přesto, že koncentrace Ni v roztoku byla vyšší než Co. Pochopení anomálního chování může vést k lepší kontrole depozitního procesu a k objasnění mechanismu spoluvylučování Ni+Co.
