Abstract

Abstract: Super-hydrophobic stainless-steel surface (SHSSS) was prepared by simple chemical etching method using ferric chloride ethanol solution and nutmeg acid ethanol solution as etching and modification solution respectively. Characterization analyses, including water contact angle (WCA) determination, Fourier-transform infrared spectrometry (FTIR), scanning electron microscopy (SEM), energy dispersive spectroscopy (EDS) and electrochemical workstation were performed on SHSSS.The stainless steel etched with ferric chloride (20 wt%) ethanol solution for 1 h, modified with nutmeg acid, and obtained super-hydrophobic properties (WCA = 151.6 °). Furthermore, the SHSSS has satisfactory chemical stability and corrosion resistance. The surface can maintain super-hydrophobicity within 3.5 wt% NaCl solution of 2 days. The corrosion inhibition efficiency calculated by the fitting parameters of Tafel polarization curve is 81.8%.
