Summary: By using a chemical treatment, a copper oxide layer with a hierarchical structure was formed in situ on a copper surface, resulting in a durable superhydrophobic surface with corrosion resistance. The stability of the oxide and the hierarchical structure contributed to the enhanced corrosion resistance and superhydrophobic durability. SEM, EDS, XPS, FT-IR, and XRD were used to characterize the surface morphology, composition, and phase structure. Wettability tests were conducted to investigate the superhydrophobicity of the surface. Acidic and alkaline solution contact angle tests, water immersion tests, and UV irradiation tests were performed to evaluate the superhydrophobicity durability. Electrochemical tests were carried out to examine the corrosion resistance of the superhydrophobic specimen by analyzing potentiodynamic polarization curves and electrochemical impedance spectra.

Summary: Corrosion is a pervasive issue in various fields, leading to material degradation, environmental pollution, economic loss, and safety accidents. Superhydrophobic coatings have been considered a promising approach for corrosion inhibition due to their special surface functionalities, but their widespread application is hindered by mechanical and chemical weaknesses. A fluorine-free dual-layer microarc oxidation/superhydrophobic coating has been developed for corrosion protection, maintaining superhydrophobicity under various conditions and exhibiting significantly enhanced impedance modulus and corrosion inhibition efficiency. The synergistic effects of the microarc oxidation layer and superhydrophobic layer contribute to the enhancement of surface multifunctions, making the dual-layer coating a potential candidate for material protection applications.
