Laser structuring

During structuring, the laser creates regularly arranged geometries in the layer or in the base material, so that the technical characteristics are changed in a targeted manner and a new functionality is developed. One example: scoring or applying small (oil) depressions for defined sliding properties. The individual elements of such a structure often measure only a few micrometres. Short laser pulses with very high pulse power generate such high energy densities that the material usually evaporates immediately (sublimation). Each laser pulse produces a small depression, melt is predominately prevented.

Certain properties are generated by laser structuring which, for example, have an effect on the friction characteristics or electric and thermal conductivity. In addition, laser structuring increases the adhesive strength and longevity of the workpiece.

What are the benefits of laser structuring of surfaces?

Environmentally friendly

No additional blasting agents or chemical substances which would prove elaborate and expensive are needed for structuring surfaces.

Reproducible and precise

The laser achieves controlled structures, precise down to the micrometre and which are very easy to reproduce.


Compared to mechanical tools which can wear out quickly, the laser is non-contact and therefore absolutely wear-free.

No post-processing

No melt or other processing residue is left on the component with laser processing.

How does the laser structuring procedure work with metal?

Regularly arranged geometries are generated in surfaces in a reproducible way using laser radiation (usually pulsed). The laser beam melts the material in a controlled manner and solidifies into a defined structure thanks to appropriate process management.

  1. The laser radiation hits the workpiece surface.
  2. The laser radiation heats the absorbing material.
  3. Structures are generated as the melt solidifies.
