摘要
本研究采用新型辊涂技术制备了氮掺杂石墨烯（NG）涂层 6061 铝合金（NG/Al）。通过拉曼和 X 射线光电子能谱分析（XPS），研究了等离子体处理获得的不同石墨化氮含量的 NG 薄膜。电化学阻抗光谱、极化曲线和浸泡试验被用来研究薄膜的腐蚀行为。结果表明，由于铝基底和氮化镓之间的粘附力增强，氮化镓/铝表现出更强的耐腐蚀性能。尤其是石墨化氮含量最高的 NG/Al 对 0.5 M H2SO4 和 3.5 wt% NaCl 的耐腐蚀性能更优。
Key role of graphitic-N in N-doped graphene coated Al alloy in corrosion resistance performance
In this study, nitrogen-doped graphene (NG) coated 6061 Al alloy (NG/Al) was prepared using a novel roll-coating technique. Through Raman and X-ray photoelectron spectroscopy analyses (XPS), the NG films with varying graphitic-N content obtained by plasma treatment was investigated. The electrochemical impedance spectroscopy, polarization curve, and immersion test were used to study the corrosion behaviors of the films. The results show that NG/Al exhibits enhanced corrosion resistance properties due to the enhanced adhesion between Al substrate and NG. In particular, the prepared NG/Al with the highest graphitic-N content shows superior resistance against both 0.5 M H2SO4 and 3.5 wt% NaCl.
期刊介绍：
The journal Carbon is an international multidisciplinary forum for communicating scientific advances in the field of carbon materials. It reports new findings related to the formation, structure, properties, behaviors, and technological applications of carbons. Carbons are a broad class of ordered or disordered solid phases composed primarily of elemental carbon, including but not limited to carbon black, carbon fibers and filaments, carbon nanotubes, diamond and diamond-like carbon, fullerenes, glassy carbon, graphite, graphene, graphene-oxide, porous carbons, pyrolytic carbon, and other sp2 and non-sp2 hybridized carbon systems. Carbon is the companion title to the open access journal Carbon Trends. Relevant application areas for carbon materials include biology and medicine, catalysis, electronic, optoelectronic, spintronic, high-frequency, and photonic devices, energy storage and conversion systems, environmental applications and water treatment, smart materials and systems, and structural and thermal applications.
