The effect of a strong magnetic field (1-12 T) on the process of Mo-Se thin coating electrodeposition was studied. The magnetohydrodynamics effect enhances the rate of ions’ convection which has strong impact on the mass transport and electrochemical reactions. The process of deposition was conducted from sulphate solutions containing Na2MoO4, H2SeO3 and Na2SO4 on a copper electrode under potentiostatic conditions. The obtained coatings were characterized by X-ray diffraction, wavelength X-ray fluorescence and, additionally, the morphology of the deposits was analyzed by scanning electron microscopy. Figs 6, Refs 37.
