Abstract
Known doctor rods ( ) used as dosing elements in coating devices have a cylindrical steel base body on whose cover surface a chromium or ceramic layer of hard material is applied. According to the invention, the cracks and craters in the layer of hard material are closed by a joint which is produced by means of an ion implantation process, by the hard material reacting with the ions applied in a plasma. The improved doctor rods have a longer service life than known doctor rods.
