Sažetak
Aluminium alloys with magnesium are of special importance for technical applications. They are
used as an important construction material in shipbuilding and in conditions which require high
corrosion resistance, especially in sea water and near the sea. These alloys are also important
in manufacture of equipment for the chemical and food-processing industry. The presence of
aggressive ions, like chloride, leads to a strong local attack due to adsorption of these ions to
those areas of the surface where the oxide film is weaker. Application of organic inhibitors in
highly corrosive media is a widely spread method of minimising corrosion damages in a number
of technologies. However, most commercial inhibitors used for this purpose are toxic and their
replacement with other non-toxic ones in the future is unavoidable. The aim of the present
study was to find less toxic inhibitor compounds for aluminium alloy corrosion. To that purpose
the extract of rosemary leaves was tested for efficiency as a corrosion inhibitor for the Al-2.5Mg
alloy. Rosmarinus officinalis L. is an aromatic plant of Mediterranean origin with outstanding
antioxidant and antimicrobial properties. Extract examined is an effective inhibitor of the
localized attack. The inhibitory action decreases with the decreasing concentration of additive.
