Electrodeposition of iron-molybdenum alloy from ammonia-citrate electrolyte

Abstract

Fe-Mo deposits were obtained from ammonia-citrate electrolyte at the potentials to the negative of -0.8 V (NHE). The method of X-ray photoelectron spectroscopy was used to establish that iron and molybdenum are included in the metallic form into the coating formed on the cathode. In the range of potentials of −0.90 to −1.10 V, the ratio between partial current densities of iron and molybdenum electrodeposition remains practically constant, which is the cause of independence of the chemical composition of the alloy on the current density in a wide range of potentials.
