Fibre Laser Texturing for Surface Functionalization

Textured surfaces exhibit improved properties in terms of tribological, biological, optical, or wetting performance once the texture is opportunely tailored for purpose. Fibre lasers provide a flexible solution for texturing different materials with different surface structures. In this work, the use of a Q-switched fiber laser for surface texturing for tribological, adhesion and biomedical applications is demonstrated. The required surface pattern of the application is investigated along with the processing conditions to realize the pattern. Results show the adaptability of the ns pulsed fibre laser to achieve various patterns with high productivity and industrial robustness.
