Solution For Electroplating Iron, And Electroplated Steel Sheet Manufactured By Using Same

Abstract: The present invention relates to a solution for electroplating iron, comprising: iron ions comprising first iron ions and second iron ions; a complexing agent; and unavoidable impurities, wherein the amount of second iron ions among the iron ions is 5 to 60 wt%. According to the present invention, electroplating efficiency is high, there is no drop in electroplating efficiency due to a continuous plating operation, and sludge generation is prevented, and, thus, the plating solution is easily managed. Burning can be prevented even in a high current density operation, and, thus, a high-quality iron-plated layer can be achieved. The plating solution does not need to be replaced, as the concentration of second iron ions generated by a plating reaction is kept constant, and, thus, the present invention is appropriate for a continuous plating process.
