Functionalized Nickel-Graphene Coatings for Tribological Applications

Graphene is one of the most interesting materials because of its multiple properties that span from structural applications to energy management applications. The use of coatings composed of a metallic matrix (MMC) with graphene is currently one of the most intriguing application aspects of this innovative material, both for scientific research and industrial applications. Electrodeposition is one of the processes that can be easily implemented on an industrial scale, characterized by high cost-effectiveness and limited equipment complexity. In this experiment, the influence of current density on the morphological characteristics, thickness, and tribological performance of nickel-based coatings reinforced with simple graphene oxide (GO) and functionalized with amino-benzene (frGO) was investigated. The results allowed for the identification of interesting process parameters for controlling the process variables based on the desired outcomes, and future experimental plans were formulated to selectively investigate crucial aspects for increasing the amount of graphene within the coating.
