Abstract
The determination of the structure of the passivation film on samples of cathodicaly treated tinplate was attempted by transmission electron microscopy.
By means of ring diffraction patterns the structure was identified as mainly fine grained polycrystalline SnO2 (tetragonal crystal structure) as well as lower oxides of tin in a continuous film. Single crystal diffraction patterns were recorded, showing evidence for particles of metallic β-Sn, metallic chromium and Cr2O3 (hexagonal crystal structure).
