Résumé:
Abstract In this work we are interested in the study of the electrochemical, morphological and structural characteristics of thin films of the Fe-Cu alloy, obtained by electrodeposition on a ruthenium substrate from a sulfate bath. The kinetic study of Fe-Cu deposition and the optimization of the electrodeposition conditions of the Fe-Cu alloys. The analysis of transient currents using the theoretical model of Scharifker-Hills indicates that the alloy's nucleation-growth mechanism does not correspond to the progressive model or the instantaneous model. The characterization of the samples was determined by an atomic force microscopy (AFM) X-ray diffraction (XRD); the morphology of the deposits obtained becomes increasingly fine by diminishing the potential. X-ray diffraction analysis showed that the films crystallize in varieties –of phase: a mixture of Cu fcc and Fe bcc structures.
