Summary:Title screen
A novel two-step approach has been developed for the creation of wear-resistant superhydrophobic coatings on metals and alloys. In the first step, a well-developed multimodal micro- and nanoscale surface roughness is formed by nanosecond laser radiation treatment. The second stage involves reducing the surface energy through deposition of low-temperature thermolysis products from hydrocarbon-containing liquids onto the textured surface. Hydrophobization is achieved due to functional groups such as CH₂ and CH₃ present in the thermolysis products. A wide range of accessible carbon-containing liquids can be used as raw materials for hydrophobization, including waste oils. The analysis of the obtained coatings was conducted using scanning electron microscopy (SEM) and atomic force microscopy (AFM) to study their morphology and roughness. X-ray photoelectron spectroscopy (XPS) and Fourier transform infrared spectroscopy (FTIR) were employed to determine the chemical composition and confirm the presence of hydrophobic functional groups. Chemical resistance tests and abrasion durability testing (using the oscillating sand method) demonstrated that the coatings on AlMg3 alloy retain their superhydrophobic properties even after aggressive exposure. These high performance indicators suggest promising applications for these coatings under real industrial conditions, particularly for protecting equipment components against corrosion, ice formation, and biofouling
