在酸性硫酸铜镀液中,采用复合电沉积技术制备了铜-纳米石墨复合材料。观察了复合镀层的微观形貌,测试了复合镀层的硬度和摩擦磨损性能。研究发现:纳米石墨的添加量为7~10g/L时,镀层具有优良的摩擦磨损性能,且镀层的制备成本较低

Copper nano-graphite composite materials were prepared by electrodeposition in an acidic copper sulfate solution. Morphology of the surface coating was observed. The hardness and friction and wear properties were tested. Experimental results show that the composite materials have good friction and wear properties and the costs are lower when the addition of nano-graphite is 7~10 g/L.
