The cross-sectional structure of a silica-added chromate film on electrogalvanized sheet steel was studied by TEM, XPS, and GDS. The results were as follows: 1) the chromate film thickness was about 100nm; 2) the chromate film consisted of aggregated silica and chromate which consisted of Cr3+ and Cr6+; and 3) the composition of silica and chromate was constant in the cross-sectional direction except at the surface where bare silica was exposed.
