Electrodeposition of Sn and Co coatings from citrate solutions

Electrodeposition of Sn and Co coatings from citrate solutions Optimal conditions for Sn and Co codeposition were achieved in slightly acid citrate solutions containing no excess of ligand. Sn–Co coatings were deposited with amounts of Co ranging from 15 to 86 mass %. Bright deposits were obtained when the Co content exceeded 76%. These coatings may be considered as solid solutions of tin in α-Co and β-Co. The β-Sn phase is predominant in the case of coatings containing less Co. Voltammograms of the partial processes of Sn(II) and Co(II) reduction may be described quantitatively with the proviso that SnL2− and CoLH− are electrically active complexes. http://www.deepdyve.com/assets/images/DeepDyve-Logo-lg.png Journal of Applied Electrochemistry Springer Journals

Abstract

Optimal conditions for Sn and Co codeposition were achieved in slightly acid citrate solutions containing no excess of ligand. Sn–Co coatings were deposited with amounts of Co ranging from 15 to 86 mass %. Bright deposits were obtained when the Co content exceeded 76%. These coatings may be considered as solid solutions of tin in α-Co and β-Co. The β-Sn phase is predominant in the case of coatings containing less Co. Voltammograms of the partial processes of Sn(II) and Co(II) reduction may be described quantitatively with the proviso that SnL2− and CoLH− are electrically active complexes.
