Peculiarities of Electroplating Tantalum Coatings from Fluoride Melts V. A. Pavlovskii Baikov Institute of Metallurgy and Material Science, Russian Academy of Sciences, Moscow, Russia Received April 13, 2006 Abstract — Electroplating tantalum coatings on molybdenum, copper, and steel is studied. The effects of various factors (the composition of a fluoride bath, its temperature, current density, and the electric charge spent) on the electrocrystallization of the deposit, its roughness, the degree of dendrite formation, current efficiency, and a possibility to plate multilayer coatings and produce tantalum wares by electrotyping are investigated. To compare the characteristics of the coatings, the studies in a standard chloride–fluoride salt system containing potassium fluorotantalate (K2TaF7) were also carried out under similar conditions.
