Abstract
A superhydrophobic coating (SHPC) on steel obtained by electrodepositing copper and zinc followed by treatment with an ethanol solution of myristic acid is characterized by a contact angle of 157 ±2°. Exposure of coated steel samples for 10 days in the gas and liquid phases of NACE and NaCl (50 g/L) solutions containing 400 mg/L H2S demonstrated a protective effect of over 90% in the gas phase and approximately 15% lower in the liquid phase. At the same time, the coating's superhydrophobicity was maintained. Using potentiodynamic polarization and impedance spectroscopy, it was shown that in a NACE+400 mg/L H2S environment, the coating slows down the anodic process on steel.
