Summary:The presence of copper-containing intermetallide phases significantly decreases the corrosion resistance of 1441 aluminum alloy. Because the possibility of the preparation of high-performance conversion coatings (CCs) in IFKhANAL-3 chromateless solution, which have protective properties that are no worse than those of chromate CCs according, has been previously demonstrated, the effect of various complexing agents on the oxidation of 1441 alloy and the protective properties of the CCs on it have been further studied. It has been shown that CC-modifying additives adsorb corrosion inhibitors and increase their protective properties.
