Abstract

Micro/nanostructure introduced by femtosecond laser surface process (FLSP) is a key factor contributing to its special wetting property. Imprinting is one of most commonly used technologies for manufacturing this structure. This study combined two technologies, providing a new method to produce superhydrophobic surface for mass production. The experimental results have proved that the counter-metal surface (aluminum 6061) of FLSP structure varies from hydrophilic to hydrophobic by changing the pressure, temperature and deposition conditions. During the imprinting process, little FLSP die surface (tungsten carbide) degradation was observed. Superhydrophobic iron alloy surface is also expected by applying the method mentioned above.
