Abstract
The surface of a rolling mill roll is coated with a coating comprising a metallic substance and is then marked by means of an intermittent laser beam. As a result, micro-craters are formed which penetrate the roll and which have rims containing components from the roll and the coating. The longevity of the roughness of the roll can thereby be enhanced.
