Procedure

FIG. 1 is a view showing the relationship between the amount of tin oxide and the amount of coating deposition converted to zirconium in the case of treating tin-plated steel sheet (tin deposition amount on one surface: 2.8 g/m2), dipped in sulfuric acid (dipped in 2% sulfuric acid (25° C.) for 0 to 60 seconds) to remove the tin oxide, by zirconium sulfate electrolysis (electrolytic conditions: 1 A/dm2×5 seconds (40° C.)) to form a chrome-free foundation layer containing zirconium (zirconium compound coating).
