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.
