Abstract

In order to enhance the corrosion resistance of low carbon steel in NaCl solution,a facile one-step electrochemical etching and lubricant injection method were used to construct a slippery lubricant-infused porous surface (SLIPS) on low carbon steel.The influence of the concentrations of hydrochloric acid and perfluorolauric acid on the contact angle of the obtained porous surface was investigated.The anti-corrosion property of the fabricated superhydrophobic surface (SHS) and SLIPS on low carbon steel was evaluated by potentiodynamic polarization curve analysis and electrochemical impedance spectroscopy (EIS) in a 3.5%(mass fraction) NaCl solution.It was revealed that when the concentrations of hydrochloric acid and perfluorolauric acid were adjusted to 0.02 mol/L and 0.8 mmol/L, respectively, the contact angle reached 151°.After silicone oil was infused into the prepared SHS, the contact angle was reduced to 106°.Results from potentiodynamic polarization suggested that both the anodic and cathodic reaction rates were simultaneously suppressed by the designed SHS and SLIPS on low carbon steel.A lower corrosion current density was exhibited by the prepared SLIPS on low carbon steel, and the corrosion protection efficiency was calculated to be 99.7%.EIS measurements revealed that the charge transfer resistances of the designed SHS and SLIPS on low carbon steel were measured to be 7 384 Ω∙cm2 and 22 635 Ω∙cm2, respectively.Superior corrosion protection performance was demonstrated by the fabricated SLIPS.The SLIPS on low carbon steel prepared from a facile electrochemical etching and lubricant injection method on low carbon steel was expected to extend the practical applications of low carbon steel materials.
