Preparation and Detection of Graphene Coating on Aluminum Magnesium

AlCl₃+LiAlH₄ THF-C₆H₆ electroplating scheme was adopted to prepare graphene coating on Al-Mg. The orthogonal test scheme was designed by SPSS software, and two indexes were tested under microhardness tester and friction tester, respectively. The optimum parameters of graphene content, current value, rotational speed and plating time were obtained. Finally, a series of spectroscopic measurement were carried out to characterize the existence of graphene, the co-deposition of elements in the coating.
