摘要:
A method for producing a surface-treated steel sheet (1), comprising: forming a phosphate compound layer (20) on a tin-plated steel sheet (10) by means of cathode electrolytic treatment, wherein the tin-plated steel sheet is obtained by tin-plating a steel sheet (11); and forming an aluminum-oxygen compound layer (30) on the phosphate compound layer by means of electrolytic treatment using an electrolytic treatment liquid containing aluminum. of the profile derived from tin phosphate (tin oxide/tin phosphate) is 6.9 or more.
摘要:
A chemical treatment steel sheet includes a steel sheet; a Fe-Sn alloy layer which is formed on at least one surface of the steel sheet; an Sn layer which is formed on the Fe-Sn alloy layer; and a chemical treatment layer that is formed on the Sn layer, and contains a 0.01 to 0.1 mg/m 2 of Zr compounds in terms of an amount of metal Zr and 0.01 to 5 mg/m 2 of phosphate compounds in terms of an amount of P. The total Sn content of the Fe-Sn alloy layer and the Sn layer is 0.1 to 15 g/m 2 of Sn in terms of the amount of metal Sn.
