The galvanostatic anodizing results of specially prepared high-purity aluminum in aqueous solutions of complex compounds K 3 [Co(C 2 O_4)_3] and K 2 [Zn(edta)] of various concentrations in the current density ranges 1.5-1.10·10 2 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 K 2 [Zn(edta)] and monolithic for K 3 [Co(C 2 O_4)_3]
