Abstract
A method for structuring at least one sliding surface (4) of a machine element (1), wherein the at least one sliding surface (4) is provided by a first structuring method with a first microstructure (5) 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 (4), by which a second microstructure (6) is defined with less depth in comparison with the first microstructure.
