Resumen
In this report we track the structural changes suffered by ITO along galvanostatic polarization at differentcurrent densities by X-ray diffraction and SEM micrographs. The XRD shown that cathodic treatmentinduces structural change in ITO, characterized by appearing peaks set distinct from ITO original structureassociated to metallic phase of the solid solution of In-Sn. It is interesting to note that although thedifferent ions present in the solution are not, at least to a noticeable degree, incorporated in the metallicphase, the SEM images show that they do influence its formation, pointing to some type of adsorptivemechanism of the inert ions during the lateral diffusion of the metallic ions.
