“…Chemical analysis of the nanoparticles deposited from a laser jet during laser ablation for the case of single-pulse nanosecond treatment in the presence of atmospheric oxygen 44 showed complete oxidation of aluminum to Al 2 O 3. The EDS spectra obtained in our study for the top layers of the coating on both types of samples (marked by the rectangle c in Figure 3a, b) prior to their fluorination indicate a very high proportion of oxygen (see Figure 3c).…”

We report a new efficient method for fabricating a superhydrophobic oxidized surface of aluminum alloys with enhanced resistance to pitting corrosion in sodium chloride solutions. The developed coatings are considered very prospective materials for the automotive industry, shipbuilding, aviation, construction, and medicine. The method is based on nanosecond laser treatment of the surface followed by chemisorption of a hydrophobic agent to achieve the superhydrophobic state of the alloy surface. We have shown that the surface texturing used to fabricate multimodal roughness of the surface may be simultaneously used for modifying the physicochemical properties of the thick surface layer of the substrate itself. Electrochemical and wetting experiments demonstrated that the superhydrophobic state of the metal surface inhibits corrosion processes in chloride solutions for a few days. However, during long-term contact of a superhydrophobic coating with a solution, the wetted area of the coating is subjected to corrosion processes due to the formation of defects. In contrast, the combination of an oxide layer with good barrier properties and the superhydrophobic state of the coating provides remarkable corrosion resistance. The mechanisms for enhancing corrosion protective properties are discussed.

“…A better fundamental understanding of laser-matter interaction is essential to precisely control the modification of materials at the nanoscale [22][23][24][25][26][27][28][29]. This way, some studies have investigated the surface modifications induced by laser treatment in terms of morphology, oxidation, hardening and thermal stresses [30][31][32][33][34][35][36][37]. The residual stresses induced by laser shock peening and present in femtosecond laser-induced periodic surface structures (LIPPS, ripples) were analyzed in [33,[38][39][40].…”

An experimental method for fabrication of a nanocomposite metamaterial based on a self-assembly of titanium dioxide microtubes with encapsulated gold nanoparticles (NPs) is proposed. The formation of microtubes is induced by laser irradiation in the presence of an external magnetic field. It is shown that the variation of the metal NP concentration leads to the increase of the optical absorption of the metamaterial. The possibility of using arrays of oriented microtubes as absorbing n-doped layers for solar cells is demonstrated.
