“…In a previous work, we investigated the effect of changing the choline chloride/ethylene glycol molar ratio in the bath on film composition, fixing the other electrodeposition parameters [32]. In more recent times, we have demonstrated the possibility to obtain high purity films [33] from a simple ethylene glycol solution containing the precursor salt, limiting the concentration of chlorides of about one/two orders of magnitude with respect to 1ChCl:2EG DES. The final deposits showed a much better corrosion performances than the analogous ones obtained from urea/choline chloride-based DES (1ChCl:2U) [34], demonstrating the effectiveness of this approach.…”

“…Alternative precursor salts to halides (chlorides, bromides, fluorides), with high solubility in ionic liquids, must be considered in order to have an inert environment with good conductivity (10 mS cm −1 ). Panzeri group [71] demonstrated the possibility of obtaining a potentially high quality deposit by reducing the concentration of chloride in the ionic liquid-based plating system. Though the release of chlorine gas was controlled to an extent, they failed to maintain the conductivity.…”

Zinc (Zn) and zinc–nickel (Zn–Ni) electrodeposition has been widely used in many industries, such as automotive and aerospace, for corrosion protection of steel components owing to their excellent corrosion resistance. Conventional zinc and zinc–nickel electrodeposition is performed in different types of aqueous baths (acid and alkaline). Such electrolytes suffer from certain drawbacks such as hydrogen gas evolution, low coulombic efficiencies, and environmental toxicity. Electrodeposition of Zn and Zn–Ni alloys from ionic liquids has gained significant attention in aerospace and automotive sectors owing to the different environments they provide for electrodeposition. This paper reviews the progress in deposition of zinc and zinc-nickel alloys in non-aqueous systems, especially ionic liquids. In addition, the challenges and technological developments associated with the Zn and Zn–Ni deposition on different substrates and the factors that need to be considered while electroplating at an industrial scale are discussed.

“…Another promising way to avoid oxygen codeposition is electrodeposition from non-aqueous baths. Although nanocrystalline, oxygen-free iron deposits have recently been obtained with this method [26], the low current densities impede the preparation of quasi-bulk material as intended in the present work.…”

A new citrate-based electrolyte is proposed for the electrodeposition of thick Fe-C films. The structure and properties of the deposits are compared to those from another electrolyte previously reported in the literature. Both consist of a nanocrystalline single-phase structure with a grain size of 20 nm, which results in a hardness of up to 660 HV. Due to its higher growth rate, the new electrolyte is a promising candidate for the deposition of thick films. However, the codeposition of oxygen causes embrittlement, limiting the application of the deposits from both the new and the known electrolyte. On the other hand, the codeposited carbon and oxygen provide considerable thermal stability and even a hardening capacity upon annealing. The results are compared and discussed with respect to the previous investigations of electrodeposited Fe-C alloys.
