| Résumé : | An apparatus was built in our laboratory in order to electrolyze a Gokhale solution (CuC10.7N,NaC14N, HC10.5N)for extended periods of time under current densities ranging from 50 to 600 A/m 2 at temperatures between 20 and 50°C The influence of the diaphragm, temperature, current density and duration of the electrolysis in pure solutions was investigated, and the results were interpreted in terms of current efficiency, overall voltage drop and specific energy consumption. The structure of the deposits was investigated by profilometry, optical micrography, scanning electron microscopy and X-ray diffraction. The structure of the deposits is not significantly different from that obtained in pure sulfuric acid solutions, but it shows an increased tendency to growth of rather large elongated crystals protruding in the electrolyte. Both types are characteristic of deposits obtained at rather low inhibition, according to Fischer's classification. © 1977 The Metallurgical of Society of AIME. |
