Abstract
The invention relates to a process for electrochemically removing a coating from coated workpieces by means of a voltage applied in an electrolyte bath between the workpiece and a counter-electrode. According to the invention, a rising voltage profile is selected during the coating removal process. This has the effect that the voltage applied at the start is low, and therefore the workpieces are not damaged, but nevertheless the rise in the voltage prevents the coating removal process taking an uneconomically long time.
