Abstract
The invention relates to a device and a method of applying a coating on a workpiece by electrodeposition. In the method, a workpiece is mounted on the mandrel of a lathe. A vessel, connected to a current generator and containing a bath of electrolyte and a conductor forming an anode, is placed beneath the workpiece. All or part of the workpiece is immersed in the bath by moving the vessel into a first position. The workpiece is turned by the lathe so that the entire surface of the workpiece is immersed at least once in the bath while a material is electrodeposited on the workpiece. The vessel is moved into a second position to break contact between the workpiece and the bath of electrolyte.
