Abstract
The effect of MAO coatings on the electrochemical behavior of aluminum composites without additives and doped with copper (1, 2, 3 wt%) in 3% NaCl solution compared to uncoated aluminum composites has been studied. A comparison of the polarization dependences of the current density lgi on the potential E of coated and uncoated aluminum composites showed the positive effect of MAO coatings on the electrochemical properties. It is shown that the presence of copper affects the electrochemical characteristics of composites with MAO coatings as compared to composites without additives. The values of current densities on the anode curves of MAO-coated aluminum composites with 1, 2, and 3% copper are not significantly different. On the local areas of the coatings the oxide-chloride compound islands were found after electrochemical tests.
