摘要:
本文针对碳钢在海洋环境中腐蚀严重的问题，采用水热法结合化学气相沉积技术及注入润滑油的三步法在碳钢表面制备了Cu/Ni复合仿生超滑表面。研究了仿生超滑表面对碳钢基体的腐蚀防护性能的影响。通过扫描电镜（SEM）、X射线光电子能谱（EDS）分析了碳钢表面水热反应2 h后形成的Cu/Ni涂层的形貌及组成成分；通过接触角测试分析了Cu/Ni疏水表面的润湿性；运用动电位极化曲线和交流阻抗谱（EIS）研究了仿生超滑表面在3.5 wt.% NaCl溶液中的耐蚀性能。结果表明，Cu/Ni膜层呈现微纳米级粗糙结构，Cu/Ni膜层疏水涂层与水滴的接触角为127.8±1°，Cu/Ni仿生超滑表面腐蚀电流密度为2.96×10-7 A·cm-2，相比于碳钢基体降低了2个数量级，对碳钢基体具有一定腐蚀防护作用。
Abstract:
In this paper, in view of the serious corrosion problem of carbon steel in marine environment, the Cu/Ni composite bionic super-smooth surface was prepared on the carbon steel surface by hydrothermal method combined with chemical vapor deposition technology and lubricant injection method. The effect of bionic super-smooth surface on the corrosion resistance of carbon steel matrix was studied. The morphology and composition of Cu/Ni was analyzed by scanning electron microscope (SEM) and energy-dispersive X-ray spectroscopy (EDS). The wettability of Cu/Ni hydrophobic film was tested by contact angle measurement. The corrosion resistance of bionic super-smooth surface was studied in 3.5 wt.% NaCl solution by potentiodynamic polarization and electrochemical impedance spectroscopy (EIS). The results show that Cu/Ni coating exhibits a micro-nanometer rough structure. The contact angle the hydrophobic film layer of Cu/Ni coating is 127.8±1°. The corrosion current density of the Cu/Ni bionic super-smooth surface is 2.96×10-7 A·cm-2, which is two orders of magnitude lower than that of carbon steel matrix. The super-smooth surface has certain corrosion protection effect on carbon steel matrix.
