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.

Method for producing a sliding surface on a machine element

A method for structuring at least one sliding surface () of a machine element (), wherein the at least one sliding surface () is provided by a first structuring method with a first microstructure () for holding lubricant. To be able to now realize the best possible sliding properties for the sliding surface, during the course of a second structuring method, recesses are formed in the at least one sliding surface (), by which a second microstructure () is defined with less depth in comparison with the first microstructure.

Method for structuring at least one sliding surface of a machine element

A non-return valve () having a sealing seat () having an opening () and also a resilient, flat closing element (), which covers the opening () in a closed position. In view of simple assembly of the non-return valve (), the closing element () and the sealing seat () are connected fixedly to one another and form a prefabricated structural unit ().
