In this study, the effects of electrolyte additives on the electrodeposition process were investigated using electrochemical measurements such as cyclic voltammetry, chronoamperometry and electrochemical impedance spectroscopy. The results showed that the presence of fluoride ions significantly reduce the possibility of TiO₂ formation. The addition of copper ions not only prevents lead loss at the cathode, but also leads to the formation of copper oxide on the surface at initial stages, which hinders nucleation of PbO₂. The presence of sodium dodecyl sulfate (SDS) also interferes with the nucleation process as it occupies active nucleation sites. The &alpha;-PbO₂ interlayer prevents copper oxidation and solves the problem of lead dioxide nucleation. Finally, it was found that the simultaneous use of all additives together with the &alpha;-PbO₂ interlayer has a positive effect on the coating process.</span></span></span></span></span> Lead dioxide electrode,anodic electrodeposition,chronoamperometry,cyclic voltammetry 92 105 http://ijmse.iust.ac.ir/browse.php?a_code=A-10-1247-2&slc_lang=en&sid=1 Hadi Sharifidarabad hadisharifi@metaleng.iust.ac.ir 1800319475328460019275 1800319475328460019275 No Metal Extraction Research Laboratory, School of Metallurgy and Materials Engineering, Iran University of Science and Technology, Narmak 1684613114, Tehran, Iran Alireza Zakeri zakeria@iust.ac.ir 1800319475328460019276 1800319475328460019276 No Metal Extraction Research Laboratory, School of Metallurgy and Materials Engineering, Iran University of Science and Technology, Narmak 1684613114, Tehran, Iran Mandana Adeli adelim@iust.ac.ir 1800319475328460019277 1800319475328460019277 Yes Metal Extraction Research Laboratory, School of Metallurgy and Materials Engineering, Iran University of Science and Technology, Narmak 1684613114, Tehran, Iran
