Electrodeposition of re-cu-se alloys from sulphur acidic electrolytes

The formation of the triple alloys Re-Cu-Se on the platinum electrode at volt amperemetric cycling has been studied. The investigation was carried out from sulphur acidic solution containing selenious acid, potassium perrhenate, chlorine copper. The kinetics of the processes was controlled using the measurements by the method of cyclic volt-amperometry on the device İVİUSTAT. For the analysis od composition and structure the methods of XRD (X-ray diffraction analysis) were used, and the investigation of films’ morphology on platinum and copper supports was conducted on scanning electron microscope (SEM). To depict the formation of the systems the corresponding mechanism of electrodeposition was suggested. It is shown that the process proceeds through several stages. The chemical composition of the obtaining layers of thin coatings makes up 14.7 at %Re, 39.6 at %Cu and 14.6 at % Se. The chemical composition of the obtaining films was determined using the method of atomic adsorption spectroscopy (AAS) with application of the spectrometer Perkin-Elmer.
