Sažetak
Tin is a moderately corrosion resistant material that is widely used in tinplate for food beverage. However, despite its excellent corrosion resistance, presence of oxidizing agents enhances the tin dissolution process by direct chemical attack. Dissolution of metallic tin, especially from the inside of a can body into the food content has a major influence on the food quality and may cause toxicological effects. To overcome the corrosion problem, different chemical compounds are added to the aggressive solutions. The most utilized inhibitors in food industry are nitrites and nitrates which are well-known hazardous to health. The aim of the present study was to investigate the influence of carboxylic acids (palmitic and stearic) on the corrosion resistance of tin, since they are present in fruit juices and different foodstuffs. The corrosion protection efficiency of the carboxylate coatings was investigated in a sodium chloride solution using electrochemical and spectroscopic techniques. The structural characteristics of the surface coatings were investigated using the FTIR spectroscopy and optical microscope.
