Abstract
A process for producing one-side electroplated steel sheet with the non-electroplating side having a high affinity for chemical conversion treatment is disclosed. The process comprises preparing a one-side electroplated steel sheet by applying a cathodic current thereto in an acidic plating bath simultaneously while slightly electroplating the non-electroplating surface thereof with a coating weight of 0.5 to 5 g/m.sup.2 by applying a cathodic current through said non-electroplating surface, and then applying electrolysis to said non-electroplating surface by passing an anodic current through said non-electroplating surface to thoroughly remove said electrodeposition on said non-electroplating surface.
