Abstract
The paper presents results of researches on the influence of magnetohydrodynamic (MHD) effect, paramagnetic and magnetic field gradient force on the process of electrochemical synthesis of Co-Pd alloys. Electrolysis was performed under galvanostatic conditions. Particular attention was paid to the influence of the magnetic field on the cathodic current efficiency, composition, structure and morphology of the produced Co-Pd alloys. Tests on the selection of electrolysis parameters are also described here, i.e. the concentration of Pd(NH₃)₄Cl₂ and cathodic current density, in order to obtain alloy coatings with well adhesion to the substrate.
