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
期刊介绍:
Surface Engineering provides a forum for the publication of refereed material on both the theory and practice of this important enabling technology, embracing science, technology and engineering. Coverage includes design, surface modification technologies and process control, and the characterisation and properties of the final system or component, including quality control and non-destructive examination.
