Abstract
A process for exchanging a surface layer of a moving steel strip with an iron layer of different composition (e.g., pure iron). The strip is anodically polarized in an iron-ion-containing electrolyte to erode the surface of the electrode-strip, supply iron ions to the electrolyte and electrodeposit iron onto a counterelectrode-strip moving in the opposite direction through the electrolyte. Thereafter the polarities of the electrode and counterelectrode strips are reversed so as to electrolytically erode a surface of the counterelectrode while plating substantially pure iron on the previously eroded portion of the electrode-strip.
