Electrodeposition of binary iron group (IG)–vanadium (V) alloys from aqueous citrate solutions was investigated. Addition of NH3(aq.) and increasing solution pH resulted in increased deposit V content, but non-metallic deposits were obtained at solution pH > 7. Increasing current density resulted in an almost linear decrease in V content and a sharp increase in hydrogen evolution (decreased current efficiency). In general, the amount of V deposited with the IG metal increased as follows: Ni < Fe ≪ Co. XRD spectra indicated that preferred orientations from 25 °C solutions were not displaced by elevated temperature deposits. Changes in orientation may contribute to the deposit magnetic properties; e.g., Co–V deposits with (1 0 0) planes exhibit harder magnetization than deposits with (0 0 2) planes.
