氧化石墨烯（GO）由于其特殊的结构和性质，引起了人们极大的兴趣。采用电沉积技术制备了GO基合金复合镀层。采用悬浮GO的Ni-W镀液在C45钢表面成功获得了Ni-W-GO复合镀层。将GO片均匀地嵌入到Ni-W合金基体中，研究了GO片镀层的结构、形貌、电化学性能和力学性能，并与Ni-W合金存款层进行了比较。扫描电子显微镜（SEM）和能谱仪（EDS）结果表明，少量GO片的加入使Ni-W存款层致密均匀。此外，通过电化学和摩擦系数测量证实了耐腐蚀性和耐摩擦性的改善。
Graphene oxide (GO) has received considerable interest in many researches due to its special structure and characteristics. In this investigation, GO was employed to fabricate alloy composite coating by electrodeposition technique. Ni-W-GO composite coatings were obtained successfully on C45 steel from a Ni-W plating electrolyte with suspended GO. These GO sheets were incorporated into the Ni-W alloy matrix uniformly and corresponding coatings were investigated for their structure, morphology, electrochemical and mechanical behavior and compared with that of Ni-W alloy deposit. From the results of scanning electron microscopy (SEM) and energy dispersive spectrometer (EDS) small amount of GO sheets made Ni-W deposit compact and uniform. Additionally, an improvement in corrosion and friction resistance was confirmed by electrochemical and friction coefficient measurements.
