This work investigates the feasibility of increasing the electric conductivity of an AA1370 aluminium wire by using pulse-reverse electrodeposition to realize Cu-Graphene composite coating. The graphene adopted was in the form of nanoplates (GnP). To study the effects of plating parameters, a 2 factorial plan was developed and tested. During the tests, the following process parameters were varied: the current density, the frequency and the duty cycle. The ANalysis Of VAriance (ANOVA)) was adopted to evaluate their influence on the coated wires' morphology and electrical conductivity resistance. The results show that all the tested conditions allow good compactness to the coating, and the amount of graphene is well incorporated within the microstructure of the copper deposit. In addition, in the best conditions, the electrical resistivity decreases up to 3.4% than the uncoated aluminum.
本研究通过脉冲反向电沉积制备铜-石墨烯复合涂层，探讨提高AA1370铝线电导率的可行性。所采用的石墨烯为纳米片（GnP）形式。为研究电镀参数的影响，制定并测试了二因素试验方案。试验过程中，改变了以下工艺参数：电流密度、频率和占空比。采用方差分析（ANOVA）评估其对涂层线材微观结构和导电电阻的影响。结果表明，所有测试条件下涂层均具有良好的致密性，且石墨烯在铜沉积物的微观结构中得到了良好的结合。此外，在最佳条件下，电阻率比未涂层铝降低了3.4%。
