Abstract
The invention relates to a method for producing a sliding surface on a machine element, in particular a cam follower, wherein the machine element is first provided with a coating on at least part of the surface of the machine element, into which coating a surface structure is then introduced by laser structuring. In order to be able to introduce a surface structure that does not penetrate the coating even in the case of low layer thicknesses (s) of the coating, the introduction of the surface structure is performed by laser interference structuring.
