Abstract: Electrolytic preparation of molybdenum coatings has been investigated in the molten system KF-K₂MoO₄-SiO₂. It was found that from the above system coherent smooth and well adhesive Mo-layers on electrically conductive substrates can be prepared. The influence of composition, temperature, and cathodic current density j(c) on the quality of Mo-coatings was studied. The best results were obtained with the electrolyte of the composition 85 mole % KF-10 mole % K2MoO₄-5 mole % SiO₂, temperatures 1173 K up to 1273 K, and j_c in the range 73-450 A m^-2.
