Abstract
A method for manufacturing and regenerating a functional surface of an anilox sleeve or anilox roller for a printing machine with a coating protecting against wear and corrosion. The anilox sleeve is preferably made out of a lightweight plastic on which an intermediate layer is applied and has a metal tube located above the intermediate layer. During a first phase, the worn engraving and the old layer are ground off from the cylindrical surface of the anilox sleeve, that is to say from the metal tube, and a coating, a carbidic tungsten carbide-cobalt-chromium layer (WC—Co—Cr) is subsequently applied. This carbidic layer is applied by a high-speed flame spraying (HVOF) process and subsequently functionalized by laser.
