Abstract
A workpiece has a tribologically useable surface formed as a sliding surface, lubricated by an intermediate material, for a counterpart movable relative to the workpiece in a direction of movement. The sliding surface is provided with a structure formed of a plurality of pockets. The pockets form a closed micropressure chamber delimited by the uninterrupted peripheral rim, respectively. The uninterrupted peripheral rim is a deburred structure edge. In a plan view, the pockets are elongate and have a longitudinal extension. The sliding surface has a functional roughness in the supporting areas between the pockets.
