Sažetak
Bronze artifacts are generally covered with green or blue colored corrosion products called patina, which not only enhances the good-looking, but help to protect the bronze. Because of the increased air pollution and acid rain the large collection of statues and works of art made from bronze exposed in urban environment could be damaged. This is why it is necessary to find the ways to improve the protection that the patina gives to bronze. In order to preserve metal works from the aggressive atmosphere, organic inhibitors are often employed. The inhibiting effects of two imidazole derivatives (1-phenyl-4-methylimidazole and 1-(p-tolyl)-4-methylimidazole) on patina with the composition characteristic for patina formed in urban atmosphere were examined. The results of these investigations have shown that both studied inhibitors improve protecting properties of bronze patina in simulated aggressive urbane atmosphere.
