Résumé: Ni-based systems (Ni-Mo and Ni-Mo-W) were electrodeposited on oxidized and nonoxidized carbon fibers from the electrolyte containing nickel sulphamate, sodium molybdate and sodium tungstate under potentiostatic conditions. The morphology, structure and chemical state of the components on the surface were analyzed by scanning electron microscopy (SEM), X-ray diffraction (XRD) methods and X-ray photoelectron spectroscopy (XPS). The kinetics of composite deposition and corrosion behaviour was studied. The NiMoW layers on oxidized carbon fibers possess the best catalytic characteristics for HER.
