Innovative, multifunctional microstructuring system for homogeneous micro- and sub-micrometer structures on 3D engine components
In the MIAMI project a demonstrator system is to be built for the production of homogenous micro- und sub-micrometer structures on 3D engine components. The structures should influence effective the Tribology (wear and friction). To produce tribologically effective surfaces it is important to produce optimal, homogenous structures over a large surface area of the engine components. There are various challenges concerning the machine technology, the laser beam source, the used optics and substrates. In the project the processes of Direct-Laser-Writing (DLW) and Direct-Laser-Interference-Patterning (DLIP) will be applied.
Up to now machines suitable for the production are often equipped only for the DLW process and have no process monitoring of the laser radiation. These machines are especially made for cutting, drilling and structuring of glasses and thin layers. By developing of certain modules in the MIAMI project the DLW and DLIP process are to be made more suitable for the industrial use. Therefore the following innovative modules must be newly developed, built and implemented in the demonstrator:
- New process head for process monitoring and flexible imaging beam path for a picosecond top hat laser to increase industrial aptitude
- Innovative picosecond top hat laser suitable for the DLIP process and for the formation of homogenous structures
- Modification of the DLIP setup for using the picosecond top hat laser to increase the industrial aptitude of the DLIP process for 3D engine components
