HyTex - Research project

Influence of ultrafast laser texturing on hydrogen uptake and diffusion in metallic materials

Post-doctoral fellow: Anthony NAKHOUL

ABSTRACT
 
The Hytex project focuses on optimizing metallic surfaces to enhance their resistance to hydrogen, a critical challenge in hydrogen storage and transport technologies. Using ultrafast laser texturing techniques, the project aims to create organized nanostructured surfaces on a Fe-Cr alloy. These surfaces, characterized by periodic surface structures (LIPSS), are studied to understand their impact on reducing hydrogen absorption. Experimental results showed a significant reduction in hydrogen permeation, due to the formation of a fine duplex oxide layer and changes in surface topography. This project contributes to the development of functional materials for industrial applications in hydrogen-rich environments, with implications for improving the durability and performance of materials under these conditions.
