<p>A process for pickling a scale covered solid surface of a metallic article includes contacting the substrate with a first liquid to loosen the scale but not completely remove it, followed by electrolysis in which the substrate with the loosened scale is an electrode and external electromotive force is applied to the substrate and a counter-electrode. This electrolysis completes the pickling by removing the loosened scale from the substrate.</p> |
