中文摘要:
      为了得到一种制备简便、耐腐蚀性能优良的用于舰船腐蚀防护的金属镀层,利用电刷镀技术在45钢上制备出了Ni-石墨烯复合镀层,采用扫描电镜(SEM)、能谱仪(EDS)、原子力显微镜(AFM)、Raman光谱仪对石墨烯片层和镀层微观形貌进行了表征,采用电化学实验和浸泡试验对Ni-石墨烯复合镀层的耐腐蚀性能进行了研究。结果表明:石墨烯片层进入了Ni-石墨烯复合镀层;相比Ni镀层,Ni-石墨烯复合镀层质量更优;在电化学实验和浸泡试验中,发现Ni-石墨烯复合镀层与Ni镀层相比,前者的腐蚀电位较后者正移了70mV,前者的自腐蚀电流密度仅为后者的0.34倍,前者的电荷转移电阻为后者的3.1倍;浸泡168 h后,Ni-石墨烯复合镀层的失重量仅为Ni镀层的0.47倍,说明Ni-石墨烯复合镀层的耐腐蚀性能明显增强。

英文摘要:
      In order to obtain a metal coating with excellent corrosion resistance and a simple preparation process is applied to navy vessel corrosion protection, Ni-graphene composite coating was grown on 45 steel substrates by electro-brush plating, Scanning electron microscope(SEM),energy dispersive spectrometer(EDS),atomic electron microscopy(AFM) and Raman spectroscopy were employed to characterize graphene,and morphology of the coatings, The corrosion resistance of Ni-graphene composite coatings was studied by electrochemical experiment and immersion test. Results show that the graphene layers enters the Ni-graphene composite coating, compared with Ni coating, the quality of Ni-graphene composite coating is better. In electrochemical experiments and immersion test, we found that Ni-GE composite coating compared with Ni plating, the corrosion resistance of the former than the latter is 70 mV, the corrosion current density of the former was only 0.34 times that of the latter, the former of the charge transfer resistance is 3.1 times of that for the latter; After immerse 168 h, the weight loss of Ni- graphene composite coating was 0.47 times of Ni plating layer, indicating that the corrosion resistance of Ni- graphene composite coating was obviously enhanced.
