Cover: The cover shows an illustration of the experimental set up for in‐situ investigations of the anodic metal dissolution under ECM conditions A specially designed channel flow cell is placed under an optical microscope with long distance lens. A gold disc with a small conical glass lens in the centre is embedded in the glass lid of the channel flow cell and works as cathode. The sample is placed beneath the cathode and works as anode. The gap width of the channel amounts 0.35mm. A maximum electrolyte flow rate of 12.3m/s was realized. The anodic dissolution was carried out by current controlled pulses. The test assembly allows the observation of the surface topography development of the anode as well as possible interface reactions (e.g. gas evolution). More detailed information can be found in: M.
