In the electrochemical deposition of Tantalum from ionic liquids at moderate temperatures, the preparation of purely metallic coatings with thicknesses in the micrometer range and the accurate control of the crystallographic parameters remain challenging. In this work, preliminary experiments on the influence of fluid dynamics during the electrodeposition of tantalum in the ionic liquid 1-butyl-1-methylpyrrolidinium bis(trifluoromethylsulfonyl) imide using ultrasound as an additional source of energy were carried out. This included a study on the influence of the ultrasound amplitude on the deposition rate of tantalum by using cyclic voltammetry and the in-situ electrochemical quartz crystal microbalance technique.
