FIELD: corrosion protection. SUBSTANCE: invention relates to protection of parts, machines, and constructions made from aluminum alloy and operated in water-salt media, in particular alloy D16 constructions in sea water and grounds, against corrosion degradation caused by sulfate-reducing bacteria. As corrosion inhibitors in presence of sulfate-reducing bacteria in water-salt media, triazine derivatives in amounts 5 to 15 mmole/l are used. EFFECT: prevented microbiological corrosion. 8 tbl
