<p>The method involves equipping an electrically conductive hollow post (13) i.e. cathodic erosion tool, with a profiling (15) on an interior surface area (14) in relation to a perforation (16) of a tube wall (17). The post is axially oriented to an electrically conductive tube (12) and moved with a sector angle (24) of less than 180 degrees under maintaining a work gap (19) for passage of an electrolyte flow orthogonal to a tube outer surface area (18). The tube is connected to a positive pole (21) when the post is connected to a negative pole (22) of a direct-current (DC) voltage source (23). The electrically conductive tube perforated to a stent is coated with magnesium.</p> |
