摘要:

针对无铬锌铝涂层耐蚀性不足的问题，通过超声波分散的方法制备了不同多壁碳纳米管 (MWCNTs) 含量的无铬锌铝涂层，研究了MWCNTs含量对无铬锌铝涂层宏观及微观形貌、成分、结合力及耐蚀性能的影响。结果表明：添加MWCNTs质量分数为0%~0.7%时，所有涂层外观均完整平滑，连续致密。MWCNTs含量为0.3%时，在涂层中分散良好，涂层结合力最佳，耐NaCl溶液腐蚀性能最好，且可以为基体提供良好的阴极保护作用，其自腐蚀电流密度仅为2.019×10^-5 A/cm²，阻抗模量较未加MWCNTs的涂层大一个数量级。此外，对MWCNTs影响涂层耐蚀性的机理也进行了分析。

Abstract：

Novel chromium-free zinc-aluminum coatings with different content of multi-walled carbon nanotubes (MWCNTs) were prepared by ultrasonic dispersion method. The effect of MWCNTs on the morphology, composition, adhesion and corrosion resistance of chromium-free zinc aluminum coatings were investigated by means of scanning electron microscope (SEM) and energy dispersive spectrometer (EDS) and adhesion tester as well as immersion test in 3.5%NaCl solution with electrochemical impedance spectroscopy and polarization curve measurement. Results show that when the MWCNTs content was 0%~0.7%, the coatings were smooth flat and dense, the flaky zinc powders and aluminum powders were parallel to the substrate, providing a good physical shielding. When the MWCNTs content was 0.3%, the coating had the best adhesion and showed the best corrosion resistance in NaCl solution, its free-corrosion current was 2.019×10^-5 A/cm², and impedance modulus reached 10³ Ω·cm². In addition, the mechanism of MWCNTs affecting the corrosion resistance of the coating was explored.

Key words： MWCNTs chromium-free zinc-aluminum coating polarization curve impedance spectroscopy corrosion resistance mechanism
