Abstract
This method combines etching of the strip by passing through reduced pressure electric plasma discharge zones and the direct off-line dip-coating of the etched strip in a bath of molten aluminum. The strip brought to cathode potential defilades continuously in registration with the magnet elements and anodes of a plurality of consecutively disposed magnetron devices and, therefore, directly into said molten metal bath.
