摘要: In a method for manufacturing a one-sided electroplated steel sheet by electroplating of a steel sheet in an acidic bath, an adsorption film-forming organic inhibitor is added to either (a) the electroplating solution or (b) a pickling solution used prior to electroplating and/or rinse water used for rinsing the pickled sheet in a concentration of at least 1 ppm, or it is added to (c) both the plating solution and the pickling solution and/or rinse water in a concentration of at least 0.1 ppm. The steel sheet is then passed through the inhibitor-containing solution, thereby providing a one-sided electroplated steel sheet having improved appearance and adaptability to phosphating on the unplated side.
