Abstract

PURPOSE:To improve corrosion resistance, and adherability of coating to the steel sheet having been coated, by chemical conversion treatment of the steel sheet, which has been subjected to alloying treatment after it is plated with zinc, with an aq. soln. contg. a Cr<6+> cpd. and aluminum fluoride. CONSTITUTION:A steel sheet, which has been subjected to alloying treatment after it is zinc plated, is caused to undergo chemical conversion treatment with an aq. soln. contg. a water soluble C<6+> cpd., e.g., CrO3, Na2Cr2O7 etc., and one or more members of aluminum fluoride such as Na3AlF6, K3AlF6 by immersion of the sheet into the aq. soln. or by other methods. This method allows to foam a chemically converted surface having high corrosion resistance, and excellent adherability to the coated film, and excellent corrosion resistance after coating.
