Abstract

ABSTRACT This study investigates the effects of the electroplating process parameters, such as temperature, graphene concentration in the bath and current density, on the electrical properties of a copper-coated aluminium alloy (AA6082). Based on previous experiences, a full factorial plan was developed and tested through the Design of Experiments (DOE) methodology to find a relation between parameters and properties. After validating the setup and the significance of the three input process parameters, a statistical model for copper electrodeposition is presented; the latter takes into account the physical interaction of the graphene nanoplatelets (GNP). From the results, the GNP amount is able to modify the electrical resistance of the copper coating; in detail, the resistance passes from 0.0319 to 0.02 mΩ, allowing a reduction of about 35% at the highest GNP content. Furthermore, an optimization following the new experimental model to decrease the electrical resistance of the graphene-based coating is presented. GRAPHICAL ABSTRACT

电镀工艺参数对铜-石墨烯基铝合金电阻的影响研究

摘要本研究研究了电镀工艺参数，如温度、镀液中石墨烯浓度和电流密度，对镀铜铝合金（AA6082）电性能的影响。根据以往的经验，通过实验设计（DOE）方法制定并测试了全因子计划，以找到参数和特性之间的关系。在验证了三个输入工艺参数的设置和重要性后，提出了铜电沉积的统计模型；后者考虑了石墨烯纳米片（GNP）的物理相互作用。从结果来看，GNP的量能够改变铜涂层的电阻；详细地说，电阻从0.0319到0.02 mΩ，在GNP含量最高的情况下可减少约35%。此外，还根据新的实验模型进行了优化，以降低石墨烯基涂层的电阻。图形摘要
