Summary:The lightly tin coated steel (LTS) developed for welded cans is widely used. The composition of the chromate film during passivation treatment is the key to achieve both good lacquer adhesion and weldability. XPS analysis applied to the lacquer fractured interface and the LTS surface under various passivation treatments showed that lacquer fracture is caused cohesive failure in the thick tin oxide that grows during lacquer curing baking treatment or during storage. The metallic chromium content, in the passivation film was also found to play an important role in suppressing the growth of tin oxide and to ensuring good lacquer adhesion.
