In the work, the corrosion behavior was studied focusing on the occurrence of depassivation (pitting corrosion) of tin in NaCl solution at different temperatures (from 10 to 40 o C). The anodic polarization leads to the destruction of the oxide film and local dissolution of tin. The damage to the metal surface appears in the form of tiny holes or pits, the number and density of which generally increase with increasing temperature of the solution. Tin exhibits the highest corrosion resistance at 20 o C. Indeed, under these conditions, the most positive values of corrosion potential and depassivation potential, the lowest amounts of corrosion current and passivation current, and the lowest density of extremely narrow and shallow pits were observed (the depth of the largest pit measured is only  0.35 µm). As the concentration of Cl - ions increases, the depassivation potential of Sn becomes more negative, and the polarization resistance decreases significantly. On the other hand, as the rate of change of the potential increases, the depassivation potential becomes more positive, while the value of the polarization resistance does not change, which means that the occurrence of pitting corrosion requires a certain induction time after the actual depassivation potential is built up. As the temperature of the solution increases, pitting corrosion begins to occur at more negative potentials, and the induction time for pitting corrosion becomes shorter
