Laser surface texturing: challenges and opportunities


Recent advancements in laser technology opened completely new areas of research and applications. Engineered surfaces by laser methods are particularly interesting for applications, which deal with friction and wear. Over the decades, many research projects were launched concerning the effectiveness of for example surface texturing under different frictional conditions and lubrication regimes such as hydrodynamic, mixed or boundary lubrication. Although there has been progress in the fabrication of precise surface textures and modeling of their influence, many conflicting reports still exist concerning the effectiveness of surface texturing under certain contact conditions. 

Within this research talk, a critical review about past, present and future trends concerning surface texturing should be provided. Finally, a summary of the fabrication methods will be given with respect to their typical feature sizes, costs, and processible materials.


Carsten Gachot received his PhD from the Saarland University in Germany in 2012 where he studied the effects of laser interference patterning on the microstructure and topography of metallic surfaces with a focus on tribological applications under Prof. Dr. Frank Mücklich and Prof. Dr. Martin H. Müser. Prof. Gachot was academic visitor at the tribology Group at the Imperial College London and is currently the head of the Tribology Research Group at the Vienna University of Technology.
