Abstract
The galvanostatic anodizing results of specially prepared high-purity aluminum in aqueous solutions of complex compounds K3[Co(C2O_4)_3] and K2[Zn(edta)] of various concentrations in the current density ranges 1.5-1.10·102 and 1.5-30 mA·cm-2, respectively. The kinetic features of anodizing have been established, indicating the occurrence of an oscillatory electrochemical process. Morphological features of a flaky and loose nature for K2[Zn(edta)] and monolithic for K3[Co(C2O_4)_3], uncharacteristic for anodic aluminum oxide, were revealed. The elemental composition, IR spectroscopic and photoluminescent characteristics of the formed oxides are shown. Keywords: anodic aluminum oxide, chelated complex compounds, anodizing.
