Description: Das Projekt "FLUIDSTRUC, Process and Machine Technology for Stucturing of Design Surfaces by Laser Remelting" wird/wurde gefördert durch: VolkswagenStiftung. Es wird/wurde ausgeführt durch: Fraunhofer-Institut für Werkstoffmechanik.The surface of a part or product strongly influences its properties and functions like abrasion resistance, haptics as well as the visual impression. Therefore many plastic parts have structured surfaces like leather textures on car dashboards. Usually these structures are integrated in the injection mould by photochemical etching being a time consuming and expensive process. Further-more large amounts of acids are used, and therefore it is not an environment-friendly process. A totally new approach to structuring metallic surfaces with laser radiation is structuring by remelting. in this process no material is removed but reallocated while molten. The innovation of structuring by remelting is the totally new active principle (remelting) in comparison to the conventional structuring by photochemical etching or the structuring by laser ablation (removal). The surface structure and the micro roughness result from a laser controlled self-organisation of the melt Pool due to surface tension. The project FluidStruc aims to investigate fundamentals of this new manufacturing process and to utilise the special benefits of the new active principle for industrial manufacturing. The task of Fraunhofer IWM is to investigate the microstructural and performance characteristics of these surfaces.
