Title: Durability of porous anodic alumina layers on AA1050 modified by incorporation of Cu, Ni and Cu/Ni
Keywords: AAO layers; Ni, Cu and Cu/Ni incorporation; Electrochemical

Abstract: The resistance of referent porous AAO (anodic aluminum oxide) layers and such modified by incorporation of Cu, Ni and both Cu and Ni was evaluated by performing electrochemical measurements using electrochemical impedance spectroscopy (EIS) and linear sweep voltammetry (LSV). The reported results are obtained after 168 hours of exposure to a 3.5% NaCl model corrosive medium. The acquired EIS spectra were analyzed by fitting to a suitable model equivalent circuit (MEC). Further, the estimated impedance values, acquired by the performed EIS data evaluation were further verified by Tafel slope analysis of the respective LSV curves. The results have shown that the elaborated films are sufficiently durable and can successfully be employed as primers for the deposition of other types of advanced coating layers.
