Abstract

A method was developed to obtain a durable coating consisting of zinc and graphene oxide (Zn-GO) in order to reduce the mechanical wear and tear rate of oil and gas pipelines made of steel. Graphene oxide was obtained from graphite by wet chemical oxidation (unmodified and modified Hummers’ method) using potassium permanganate and sulfuric acid. The process was carried out at various temperatures. The steel was covered with an ultrathin layer of Zn-GO using the electrophoretic deposition method. The GO particle size (< 90 nm) was confirmed by XRD and laser analysis. For GO particles obtained by the modified Hummers’ method, a significant correlation was observed in the scratch (R2 = 0.87) and the Vickers microhardness tests (R2 = 0.93), which indicates a lower wear rate of Zn-GO-coated steel.

锌与氧化石墨烯复合材料作为油气管道新型防护涂层

为了降低石油和天然气管道的机械磨损率，开发了一种由锌和氧化石墨烯(Zn-GO)组成的耐用涂层的方法。用高锰酸钾和硫酸对石墨进行湿式化学氧化(未改性法和改性Hummers法)制备氧化石墨烯。这个过程是在不同的温度下进行的。采用电泳沉积法在钢表面覆盖一层超薄的Zn-GO。氧化石墨烯粒径(<经x射线衍射和激光分析证实。对于改进Hummers方法获得的氧化石墨烯颗粒，划痕(R2 = 0.87)和维氏显微硬度测试(R2 = 0.93)之间存在显著相关性，表明氧化锆涂层钢的磨损率较低。
