One method of creating a brass coating is through electrodeposition, which is most often completed in cyanide galvanic baths. Due to their toxicity, many investigations focused on the development of more environmentally friendly alternatives. The purpose of the study was to explore a new generation of non-aqueous cyanide-free baths based on 1-ethyl-3-methylimidazolium acetate ionic liquids. The study involved the formation of copper, zinc, and brass coatings. The influence of the bath composition, cathodic current density, and temperature was determined. The obtained coatings were characterized in terms of their morphology, chemical composition, phase composition, roughness, and corrosion resistance. It was found that the structure of the obtained coatings is strongly dependent on the process parameters. The three main structure types observed were as follows: fine-grained, porous, and olive-like. To the best knowledge of the authors, it is the first time the olive-like structure was observed in the case of an electrodeposited coating. The Cu-Zn coatings consisted of 19–96 at. % copper and exhibited relatively good corrosion resistance. A significant improvement of corrosion properties was found in the case of copper and brass coatings with the olive-like structure.

The present study aims to investigate the effect of Ananas comosus juice on nickel electrodeposition on mild steel. The effect of this additive on electrodeposition behaviour, bath composition, surface morphology and corrosion performance of the nickel electrodeposited mild steel were investigated. The bath constitutents are optimized through Hull cell experiments. To investigate the nature of the deposits, FT-IR, scanning electron microscopy, EDAX, XRD and electrochemical methods are applied. Current efficiency and polarization studies were carried out. The results confirmed the influence of Ananas comosus juice on nickel electrodeposition.
