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.
Keywords
