REASON OF CORROSION OF ALUMINIUM PRODUCTS IN SEA WATER

Abstract

In this paper, the cause of corrosion of aluminium products in sea water is proposed. Corrosion is caused by incomplete oxidation of aluminum cells on the surface of products. Incomplete oxidation of aluminium cells occurs due to lack of energy in oxygen molecules. It is necessary to significantly increase the energy of oxygen molecules for oxidation the rhombic subsystem of a cubic face-centered aluminum cell. It is shown a significant decrease in the rate of the chemical reaction for the treated aluminium foil interacted with iodine in alcohol solution. The foil was in contact with oxygen heated to 450 °C and subjected to ultraviolet irradiation at the same time. It was pretreated for 12 hours. It is assumed that 12 hours of contact the foil with reactive oxygen species, most of the aluminium cells on the surface of the foil samples have been completely oxidised. This foil doesn’t react chemically with halogens.
