“…The calculated new surface level is elevated above its initial position before the irradiation by 2-3 nm due to material thermal expansion. The formation of a number of dislocation planes is visible as light blue lines in Figure 4 beginning from 300 ps due to the laser peening process [62] (see Figure S2 in Supplementary Material with the zoomed atomic snapshot at 1000 ps).…”

Understanding the mechanisms and controlling the possibilities of surface nanostructuring is of crucial interest for both fundamental science and application perspectives. Here, we report a direct experimental observation of laser-induced periodic surface structures (LIPSS) formed near a predesigned gold step edge following single-pulse femtosecond laser irradiation. Simulation results based on a hybrid atomistic-continuum model fully support the experimental observations. We experimentally detect nanosized surface features with a periodicity of ∼300 nm and heights of a few tens of nanometers. We identify two key components of single-pulse LIPSS formation: excitation of surface plasmon polaritons and material reorganization. Our results lay a solid foundation toward simple and efficient usage of light for innovative material processing technologies.

“…Different studies have been reported on assessing the role of ultrafast lasers in producing functional surfaces for wettability transitions and corrosion inhibition [ 33 , 34 , 35 , 36 , 37 , 38 ]. Ahuir-Torres et al [ 24 ] reported no change in the corrosion inhibition of AA2024-T3 after texturing with a ps laser.…”

Enhancing Anticorrosion Resistance of Aluminum Alloys Using Femtosecond Laser-Based Surface Structuring and Coating

We report a robust two-step method for developing adherent and anticorrosive molybdenum (Mo)-based coatings over an aluminum (Al) 6061 alloy substrate using a femtosecond (fs) laser. The fs laser nanostructuring of Al 6061 alloy in air gives rise to regular arrays of microgrooves exhibiting superhydrophilic surface properties. The microstructured surface is further coated with an Mo layer using the fs-pulsed laser deposition (fs-PLD) technique. The combination of the two femtosecond laser surface treatments (microstructuring followed by coating) enabled the development of a highly corrosion-resistant surface, with a corrosion current of magnitude less than that of the pristine, the only structured, and the annealed alloy samples. The underlying mechanism is attributed to the laser-assisted formation of highly rough hierarchical oxide structures on the Al 6061 surface along with post heat treatment, which passivates the surface and provide the necessary platform for firm adhesion for Mo coating. Our results reveal that the corrosive nature of the Al-based alloys can be controlled and improved using a combined approach of femtosecond laser-based surface structuring and coating.

“…[21][22][23] Femtosecond laser technology is a one-step processing approach, which has been widely used in anti-corrosion and self-cleaning, and has also been verified to be a prospective approach to manufacture superhydrophobic surfaces. [24][25][26] Boinovich et al 27 used pulsed laser treatment to prepare a superhydrophobic oxidized surface. Because of its multimodal roughness and ''air valley'' phenomenon, the local anti-corrosion ability of the coating is evidently promoted in 3.5 wt% NaCl solution.…”
