Abstract

In the present investigation, an attempt was made to electrodeposit zinc using an eco-friendly zincate electrolyte as a total substitute for cyanide solutions. Without additives the deposits are powdery and grey in appearance. Hence a systematic hull cell study was made to obtain a smooth, fine-grained semi-bright deposit over a wide current density range in presence of urea, thiourea, acetyl thiourea and N-ethyl thiourea. Current efficiency and throwing power of the solution were determined. The deposits were characterised for adhesion, porosity and hardness. Corrosion characteristics of the deposits were studied in 3.5% sodium chloride solution and the results were discussed
