abstract = {Galvanized steel surfaces are widely used in industry
as a solution to prevent corrosion of steel tools that operate in
outdoor or corrosive and oxidative environments. These objects are
coated with a zinc protective layer deposited by hot dip
galvanization. Turning the surface of galvanized steel tools into
superhydrophobic may lead to very useful functionalities, although
it may be a difficult task, because the preservation of the thin zinc
layer is a claim. We propose herein the use of a bottom-up
approach based on sandblasting, followed by sintering of zinc
nanoparticles on the galvanized steel substrate, which allowed us to
produce a zinc-made hierarchical structure required for superhydrophobicity.
These samples acquired a double-scale structure that led to superhydrophobicity when they were later
hydrophobized with a thin fluoropolymer layer. We found that sandblasting might be useful but not mandatory, unlike the sintering
process, which was essential to reach superhydrophobicity. We found that, under certain experimental conditions, the surfaces
showed outstanding water-repellent properties. We observed that the sandblasting on galvanized steel caused more damage than the
sintering process. Sintering of low-melting-point metal nanoparticles was revealed as a promising strategy to fabricate functional
metallic surfaces.},
