The Comparison of Possibilities at Using of Different Electrolytes in the Process of Anodizing Aluminum

M. Gombar, J. Kmec, Faculty of Management, University of Presov, Presov; M. Badida, L. Sobotova, Faculty of Mechanical Engineering, Technical University of Kosice, Košice, Slovakia The contribution researches and solves the suitability of utilize of electrolyte, consisting of the oxalic acid, boric acid, sodium chloride and aluminium cations in the process of anodizing aluminium in operating conditions of electrolyte T = 22 °C, t = time of oxidation and the size of at least 210 an applied voltage U = 12 V. The appropriate use of the electrolyte is judged by the thickness of the anodic aluminium oxide layer (AAO) formed on the basis of the monitoring and the resulting quality of the sample surface.
