Abstract
PURPOSE:To obtain a steel sheet having superior corrosion resistance by carrying out electrodeposition at a prescribed current density with an acidic plating bath contg. Zn ions, tervalent Cr ions and oxide colloid each at a specified concn. CONSTITUTION:An acidic plating bath contg. 10-70g/l Zn ions, 10-70g/l tervalent Cr ions and 2-200g/l oxide colloid is prepd. The oxide is selected among oxides of Zr, Ti, Sb, Sn, Cr, Mo and Ce. Electrodeposition is carried out at 70-250A/dm<2> current density with the acidic plating bath.
