中文摘要:
      为了得到性能更加优异全面的复合镀层,使用复合电沉积技术制备不同石墨烯颗粒大小的Ni-Co-石墨烯复合镀层,并制备了Ni-Co合金镀层。测试镀层的表面形貌,相结构,显微硬度,耐磨性和耐蚀性能。结果显示,石墨烯在电沉积中很好的嵌入到了镀层基质中,而且石墨烯的存在并没有改变镀层基质的晶体结构;石墨烯的填加增加了复合镀层的显微硬度,最高可达805HV;降低了复合镀层的摩擦系数,在一定程度上减少了粘着磨损的面积;复合镀层的自腐蚀电流密度可以降低到1.0905×10-5A/cm2,低于Ni-Co合金镀层的自腐蚀电流密度。说明了石墨烯的添加增强了复合镀层的硬度,耐磨性和耐蚀性。
Effect of graphene particles on the surface properties of ni-co-graphene composite coatings
英文关键词:Graphene  Composite electrodeposition  Ni-Co alloy coating
英文摘要:
      In order to obtain more excellent and comprehensive composite coatings, Ni-Co-graphene composite coatings of different graphene particle sizes were prepared by using composite electrodeposition technology, and Ni-Co alloy coatings were prepared. The surface morphology, phase structure, microhardness, wear resistance and corrosion resistance of the coating were tested. The results showed that graphene was well embedded in the coating matrix during electrodeposition, and the presence of graphene did not change the crystal structure of the coating matrix. The addition of graphene increased the microhardness of the composite coating up to 805HV. The friction coefficient of composite coating is reduced, and the adhesive wear area is reduced to some extent. The self-corrosion current density of composite coating can be reduced to 1.0905×10-5A/cm2, which is lower than that of Ni-Co alloy coating. It was shown that the addition of graphene enhanced the hardness, wear resistance and corrosion resistance of the composite coating.
