Description du projet
Un système laser innovant pour les structures de surface avancées
Les structures de surface bioinspirées offrent un potentiel commercial important pour la conception de surfaces fonctionnalisées qui répondent aux attentes des marchés industriels. Il a déjà été démontré que la texturation par laser permettait de conférer aux surfaces des fonctionnalités avancées. Le projet LAMPAS, financé par l’UE, augmentera le potentiel de la structuration laser pour la conception de surfaces récemment fonctionnalisées, ce qui améliorera l’efficacité, la flexibilité et la productivité. Ce projet repose sur le développement d’un système laser ultracourt à haute puissance, de stratégies et de concepts d’alimentation en faisceau, ce qui sera réalisé en combinant les caractéristiques des technologies de traitement par laser DLIP (direct laser interference patterning ou motif d’interférence laser direct) et polygonal. Les résultats du projet apporteront à l’industrie européenne une technologie rentable et robuste pour produire une large gamme de surfaces fonctionnelles.
Objectif
Current industrial markets demand highly value added products offering new features at a low-cost. Bio-inspired surface structures, containing features in the nanometer/micrometer scales, offer significant commercial potential for the creation of functionalized surfaces. In this aim technologies to modify surfaces instead of creating composites or spreading coatings on surfaces can offer new industrial opportunities. In particular, laser surface texturing, has shown to be capable to obtain advanced functionalities, especially when sources operating at pulse durations of nanosecond (short) and picosecond and femtosecond (ultra short) are used. LAMPAS will significantly increase the potential of laser structuring for the design of newly functionalized surfaces by enhancing the efficiency, flexibility and productivity (over 1 m²/min) of the process based on the development of a high power ultra-short laser system as well as strategies and concepts for beam delivery. This will be performed by combining the outstanding characteristics of two laser technologies, being Direct Laser Interference Patterning and Polygon Scanner processing. The expected results to be obtained in this project will provide the European industry with a cost effective and robust technology, capable of producing a broad range of functional surfaces on large areas at outstanding throughputs, bringing Europe a chance to lead in this key area of surface treatment. LAMPAS consortium covers the full value chain for laser surface texturing and has access to demanding markets. In addition, an in-line surface characterisation to enable rapid feedback about the target topography as well as to control surface temperature during the laser process will be included.
