摘要： A method for manufacturing a zinc-silica composite electroplated steel sheet, which comprises the steps of: adding, to a zinciferous acidic electroplating solution containing silica particles and nitric acid ions, a complexing agent, which is capable of forming a stable complex with zinc, in an amount within a range of from 0.001 to 10 moles per liter of the electroplating solution, or a pH buffer, which has a pH buffering effect in a solution having a pH value within a range of from 5 to 12, in an amount within a range of from 1 to 50 g per liter of the electroplating solution; and electroplating a steel sheet in the resultant electroplating solution containing the complexing agent of the pH buffer in addition to the silica particles and the nitric acid ions, to form, on the surface of the steel sheet, a zinciferous plating layer in which silica particles are uniformly dispersed.
