The electrodeposition of Sn-Zn coating at ambient temperature was investigated. The bath consists of metal salts SnCl2 center dot 2H(2)O and ZnSO4 center dot 7H(2)O and sodium citrate (NaC6H5Na3O7 center dot 2H(2)O) as complexing agent. To prevent precipitation, the pH is fixed at 5. Reducing tin and zinc through Sncit(2-) and ZnHcit(-) complex respectively is confirmed by the presence of two cathodic peaks on the voltammogram. The kinetic of tin (II) reduction process is limited by the SnCit(2-) dissociation. The SEM and TEM observations have showed that the coating consists of a uniform Sn-Zn layer composed of fine grains on which tin aggregates grow up. XRD revealed peaks corresponding to the hexagonal Zn phase and the tetragonal beta-Sn phase. (C) 2016 Elsevier B.V. All rights reserved.
