| titleOfInvention | Chemical treatment of Ni-plated steel sheet |
| abstract | PROBLEM TO BE SOLVED: To provide a method for forming a chemically treated film excellent in paint adhesion, corrosion resistance and weldability on a Ni-plated steel sheet. SOLUTION: On a steel plate plated with 300 to 2000 mg / m 2 of Ni, a bath temperature containing H 2 SO 4 of 1/50 to 1/300 by mass ratio with CrO 3 and CrO 3 is less than 45 ° C. Cathodic electrolysis of 30 A / dm 2 or more in the treatment bath, followed by cathodic electrolysis of 20 A / dm 2 or less in a treatment bath containing CrO 3 and a bath temperature of 50 ° C. or more, the metal chromium adhesion amount is 30 to 200 mg. / m 2, corrosion resistance oxide chromium coating weight is 2 to 15 mg / m 2, coating adherence, chemical treatment method superior Ni-plated steel sheet weldability. It is desirable that the concentration of CrO 3 in the cathode electrolytic treatment bath is 100 to 250 g / l, and the concentration of CrO 3 in the immersion treatment bath is 10 to 200 g / l. [Selection figure] None |
