目的 解决油气装备管道面临的腐蚀磨损等失效问题。方法 使用不同物质的量比的纳米Fe3O4、MoS2通过硅烷偶联剂(APTES)结合为杂化填料,并将其填充至环氧树脂(EP)中,制备出复合涂层。利用扫描电镜(SEM)、X射线衍射仪(XRD)及傅里叶红外光谱(FT-IR)对杂化填料的显微结构、物相组成及成分进行了分析。同时,利用分散稳定性试验、显微维氏硬度、往复摩擦试验、表面轮廓测试、吸水率及接触角测试、电化学阻抗谱及动电位极化曲线综合评价复合涂层耐磨及防腐蚀性能。结果 Fe3O4-MoS2纳米杂化物在环氧树脂中具有良好的分散稳定性。与Fe3O4/EP、MoS2/EP相比,Fe3O4-MoS2/EP复合涂层的显微硬度与耐磨性提高,同时其耐水性和防腐性能也得到增强。当Fe3O4-MoS2物质的量比为1∶5时,复合涂层摩擦因数最低为0.337,相比于纯EP降低34.56%。当Fe3O4-MoS2物质的量比为1∶1,复合涂层阻抗值最高,并且显示出最大的腐蚀电位(Ecorr)和最小的腐蚀电流(Jcorr),Fe3O4-MoS2/EP涂层的阻抗(Rc)提高了近2个数量级。结论 Fe3O4-MoS2是可用于制备高性能环氧耐磨防腐涂料的有效的纳米填料。复合涂料优异的减摩性得益于Fe3O4颗粒的纳米球滚动润滑效应和MoS2片的滑移效应,而其高防腐性能归功于Fe3O4-MoS2良好的分散性和阻隔性。 |
英文摘要: |
To improve the low corrosion and wear resistance caused by micro-pores in epoxy resin, nano-Fe3O4 was used as a filler to modify the epoxy resin. However, considering the poor dispersion and easy aggregation of the nano-Fe3O4 filler, this study used a silane coupling agent (APTES) to modify Fe3O4 and connect it to the lubricating layered molybdenum disulfide. Q235 steel was used as the substrate, polished and cleaned with sandpaper, and 1 wt.% Fe3O4-MoS2 with different molar ratios (3 : 1, 1 : 1, 1 : 3, 1 : 5 and 1 : 7) was added to the epoxy resin to prepare composite coatings. The microstructure and phase composition of the hybrid filler were analyzed by transmission electron microscopy (TEM), scanning electron microscopy (SEM), X-ray diffraction (XRD), and Fourier transform infrared spectroscopy (Nicolet 6700). The dispersion of the filler in the epoxy resin was observed with a stereomicroscope (OM), and the microhardness of the coating was tested with a micro Vickers hardness tester (HV-1000STA). Wear tests were conducted on the surface multifunctional testing machine (MFT-4000), and the morphology of wear marks was observed and elemental analysis was performed. The corrosion resistance of the coating was comprehensively evaluated by water absorption rate, contact angle test, electrochemical impedance spectroscopy (EIS), and potentiodynamic polarization tests. |
