The uniformity of the tin layer on tinplate formed along the surface roughness on steel generally decreases after the reflow. We estimated the uniformity of the tin layer by using the EPMA, and quantitatively investigated the effect of the anodic oxidation treatment prior to the reflow on the uniformity of the tin layer. The experimental results are summarized as follows. (1) The morphology of the surface of the tin layer which was reflowed after the anodic oxidation treatment was similar to that of the as electrodeposited surface. (2) The uniformity of the tin layer on tinplate was improved by the anodic oxidation treatment prior to the reflow. (3) The occurrence of the iron sulfide products, which occurred at the deformed areas on lacquered tinplates after the retort test in the solution containing sulfide ions, depended on the uniformity of the tin layers.
