Figure 1. Schematic diagram of the dissolution of a metal surface in MFB Grey/DL4 electrolyte. Metal ions (Mez+) are absorbed by the ion-conducting solid during the electropolishing process. The conductive liquid serves to reduce the resistance of the electrolyte between the anode, ion-conducting solid, and the cathode.
