Sažetak
The corrosion behaviour of tin plate in the solution of sodium chloride, acetic acid and their mixtures was investigated by the galvanostatic polarization of aluminium-steel couple. Also the influence of different atmospheres (air, oxygen, nitrogen), above and in the solutions, on the corrosion of tin plate was investigated. Measurements have shown that in all examined solutions tin plate was cathodic in relation to steel and the corrosion process is under cathodic control. The oxygen was strong accelerator of corrosion process. Mixtures of sodium chloride and acetic acid have shown as more corrosive media that the sodium chloride or acetic acid. Increase of concentration of sodium chloride and acetic acid accelerate corrosion of tin plate ; this process is specially expressed in mixtures of chloride and acetic acid solutions. On the base of these results it can be suggested that for the practical use of tin plate as a packaging materials, the content of sodium chloride shoud be the lowest as possible one. It is also suggested to avoid the presence of oxygen into the cans ; therefore it is necessary to pack foods into tin plate cans in the inert atmosphere (e.g. under nitrogen atmosphere).
