The catalytic activity towards the hydrogen evolution reaction is most likely related to the active surface area of the coatings. The different magnetic force generates an additional convection, which can affect the morphology of the deposit. The work aims to obtain Co-P alloys with a high cathodic activity for hydrogen evolution in 8MNaOH at 90\degC by electrodeposition. An external magnetic field generated by a permanent magnet was used to modify the composition and morphology of the alloy. Figs 4, Refs 13.
