Abstract
Electrochemical impedance spectroscopy (EIS) and potentiometric polarization (Tafel) tests were utilized to investigate the corrosion protection efficiency of epoxy (EP) composite coatings reinforced with aluminum powder additives deposited on carbon steel substrate. Different aluminum powders including pure aluminum (Al) and aluminum composites powders containing alumina (Al2O3) and carbon nanotubes (CNTs) were used as an additive filler. Various aluminum composite powders containing 2 wt.% of each CNTs and Al2O3 nanoparticle were synthesized using ball milling and then added into EP coating at concentration of 1 wt.%. It was found that the incorporation of formulated additive fillers improves the corrosion resistance of neat EP coating owing to enhanced barrier properties of EP composite coatings. It was also found that the barrier property of Al/CNT/Al2O3 additive is more significant than other additives owing to reduced particle size and certain shapes of particles as it further reduces the transport paths for penetration of corrosive environment through the coating and greatly prevents possible reactions at metal substrate/coating interface. Moreover, EP-Al/CNT/Al2O3 maintained one-time constant characteristic and showed the highest impedence and stability over the whole exposure time. In addition, the presence of these additives strengthens the coating, leading to further improvement of barrier property of the coating.
摘要
采用电化学阻抗谱(EIS)和电位极化(Tafel)试验, 研究了在环氧树脂涂层中添加含铝粉末以增强 碳钢基材的防腐性, 含铝粉末包括纯铝、Al/CNT、Al/Al2O3、Al/CNT/Al2O3。用球磨法合成含2 wt.% 碳纳米管、2 wt.%氧化铝纳米颗粒的复合粉末, 然后以1 wt.%的浓度加入到环氧树脂涂层中。结果表 明, 由于环氧树脂复合涂层的防护性能增强, 从而提高了其耐腐蚀性。研究还发现, Al/CNT/Al2O3复 合添加剂的保护性能比其他添加剂更显著, 因为其颗粒尺寸的减小和具有某些形状的颗粒, 进一步减 少了腐蚀环境通过涂层渗透的路径, 避免了金属基底/涂层界面可能发生的反应。EP-Al/CNT/Al2O3保 持了一次时间常数特性, 并在整个暴露时间内表现出最高的阻抗和最强的稳定性。这些添加剂的存在 增强了涂层, 从而改善了涂层的屏障性能。
