Abstract

The present paper discusses the electrodeposition of tin from an alkaline bath of SnCl2 10-1M without additives and with ethylenediamine, N,N-diethylethylenediamine and ethanolamine additives 10-2M. The investigation of the crystallization processes was made by means of electrochemical methods: the galvanostatic polarization and chronoamperometry. The galvanostatic measurements indicate that the presence of additives shifts the crystallization potential through more negative values. The morphology of metallic deposits were analysed with an Euromex microscop. The chronoamperometric data shows a 3D progressive nucleation for tin electrodeposition from alkaline bath without or with aminic additives.
