摘要：
A serial of composite coatings produced by combination of cerium sol-gel coatings and cerium conversion layers has been developed in this work: (1) sol-gel coating sealed by conversion coating; (2) sol-gel coating sealed by lowdensity sol; (3) conversion coating thickened by sol-gel coating. For both sol-gel coatings and conversion coatings, cerium chloride heptahydrate (CeCl
