  • the structure may be a uniform pattern which can be adapted to the loads which occur and which can be reproduced during manufacture.
  • the structure can be adapted to working loads in a simple manner by changing the depth of the depressions and the height of the elevations.
  • the depressions with sideward elevations are suitably designed as furrows.
  • the furrows may advantageously be straight or cross each other.
  • the furrows may also be wavy.
  • the depressions may advantageously be formed as closed pockets. As viewed from above, the pockets may advantageously have an elongated or round shape.

  • the laser structuring simultaneously permits good adaptation of the structure to the working loads.
  • the elevations are formed by displaced melt produced during processing at the structure edges, which is generated through thermal processing.
  • the height of the elevations can be adjusted via the displaced melt volume.
  • the melt volume can be varied by the processing parameters, i.e., for example, via the advance speed or via the laser parameters, i.e., for example, through adjustment of the power or the pulse duration.
  • Laser processing facilitates changes to the design of the structure, such as the surface portion of pocket structures or the angles of intersection of crossing structures.
  • the height and the width of the elevations influence the adhesion of the bearing shell in the connecting rod eye and can also be easily varied during laser processing.
