Abstract

Purpose

This study aims to explore the synergistic effect of oxide nanoparticles (ZnO, Fe₂O₃, SiO₂) and cerium nitrate inhibitor on anti-corrosion performance of epoxy coating. First, cerium nitrate inhibitors are absorbed on the surface of various oxide nanoparticles. Thereafter, epoxy nanocomposite coatings have been fabricated on carbon steel substrate using these oxide@Ce nanoparticles as both nano-fillers and nano-inhibitors.

Design/methodology/approach

To evaluate the impact of oxides@Ce nanoparticles on mechanical properties of epoxy coating, the abrasion resistance and impact resistance of epoxy coatings have been examined. To study the impact of oxides@Ce nanoparticles on anti-corrosion performance of epoxy coating for steel, the electrochemical impedance spectroscopy has been carried out in 3% NaCl solution.

Findings

ZnO@Ce3+ and SiO2@Ce3+ nanoparticles provide more enhancement in the epoxy pore network than modification of the epoxy/steel interface. Whereas, Fe2O3@Ce3+ nanoparticles have more to do with modification of the epoxy/steel interface than to change the epoxy pore network.

Originality/value

Incorporation of both oxide nanoparticles and inorganic inhibitor into the epoxy resin is a promising approach for enhancing the anti-corrosion performance of carbon steel.

氧化物纳米颗粒和无机抑制剂对环氧涂层防腐性能的协同效应

目的本研究旨在探讨氧化物纳米粒子（ZnO、Fe2O3、SiO2）和硝酸铈抑制剂对环氧涂层防腐性能的协同效应。首先，硝酸铈抑制剂被吸收到各种氧化物纳米粒子的表面。为了评估氧化物@Ce 纳米粒子对环氧涂层机械性能的影响，研究了环氧涂层的耐磨性和抗冲击性。研究结果ZnO@Ce3+ 和 SiO2@Ce3+ 纳米粒子对环氧树脂孔隙网络的增强作用大于对环氧树脂/钢界面的改性。原创性/价值在环氧树脂中同时加入氧化物纳米粒子和无机抑制剂是提高碳钢防腐蚀性能的一种可行方法。

期刊介绍： Anti-Corrosion Methods and Materials publishes a broad coverage of the materials and techniques employed in corrosion prevention. Coverage is essentially of a practical nature and designed to be of material benefit to those working in the field. Proven applications are covered together with company news and new product information. Anti-Corrosion Methods and Materials now also includes research articles that reflect the most interesting and strategically important research and development activities from around the world. Every year, industry pays a massive and rising cost for its corrosion problems. Research and development into new materials, processes and initiatives to combat this loss is increasing, and new findings are constantly coming to light which can help to beat corrosion problems throughout industry. This journal uniquely focuses on these exciting developments to make essential reading for anyone aiming to regain profits lost through corrosion difficulties. • New methods, materials and software • New developments in research and industry • Stainless steels • Protection of structural steelwork • Industry update, conference news, dates and events • Environmental issues • Health & safety, including EC regulations • Corrosion monitoring and plant health assessment • The latest equipment and processes • Corrosion cost and corrosion risk management.
