Abstract

The inhibitory effect of compositions based on sodium alginate and zinc salts on the alu­minum alloy corrosion in a chloride-containing environment was studied. It was found that the protective effectiveness largely depends on the nature of the anion in the zinc salt composition. The mechanisms of the formation of protective films on the alloy surface were characterized based on the results of electrochemical measurements, electron microscopy and energy-dispersive X-ray microanalysis. The highest corrosion resistance (96%) was demonstrated by the composition with zinc acetate, which is due to the formation of a homogeneous film with high charge transfer resistance. The composition based on zinc nitrate provided protection at the level of 93% due to surface passivation and the formation of an oxide layer. The lowest efficiency (82–83%) was shown by the composition with zinc sulfate, which is associated with the formation of less stable sorption structures.
