Corrosion behavior of tinplates covered with the molybdenum compound film was investigated in organic acid solution. Specimens treated by pulsed current in the molybdate solution inhibited anodic and cathodic reactions in organic acid solution. Corrosion current densities of these specimens were lower than the specimen without treatment. Anodic or cathodic polarization, however, caused the pitting corrosion on surface of these specimens covered with molybdenum compounds.
