摘要

为增强低碳钢在氯化钠溶液中的耐腐蚀性能，结合简易的一步电化学刻蚀与润滑油注入的方法，在低碳钢上构筑润滑液体注入的多孔表面，探讨了电化学刻蚀电解液中盐酸与全氟十二烷酸浓度对多孔表面接触角的影响规律；通过动电位极化曲线和电化学阻抗谱研究了超疏水低碳钢表面和润滑液体注入的多孔低碳钢表面在3.5%(质量分数)NaCl 溶液中的耐蚀性能。结果表明:当刻蚀电解液中盐酸浓度为0.02 mol/L，全氟十二烷酸浓度为0.8 mmol/L 时，接触角达到了151°。在获得的超疏水低碳钢表面注入硅油后，接触角降至106°；超疏水低碳钢表面和润滑液体注入的多孔低碳钢表面能够同时抑制低碳钢腐蚀过程的阳极和阴极反应，润滑液体注入的多孔低碳钢表面具有更小的自腐蚀电流密度，保护效率高达99.7%；超疏水低碳钢表面和润滑液体注入的多孔低碳钢表面的电荷转移电阻分别为7 384 Ω∙cm2和22 635 Ω∙cm2，润滑液体注入的多孔表面的耐蚀性能优于超疏水表面的。通过简易的电化学刻蚀与硅油注入的方法成功制备了润滑液体注入的多孔低碳钢表面，具有优异的防护性能，为低碳钢材料的广泛应用提供了重要保障。

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.
