▎ 摘　　要

NOVELTY - Preparing metal material coated with graphene, involves connecting a metal electrode with an anode end of a spark mixing and ablation device, connecting a graphite electrode with a cathode of the spark mixing alation device and introducing a gas into the spark-mixing and a combustion device to start the spark mixture and anion device. The metal electrode and the graphite electrodes are ignited and burned to form nano-metal particles and graphene sheets. The graphene sheet and the nano-metallic particles are collided by the gas to form the graphene sheet on the surface of the metal particles to form metal graphene sheet. USE - The method is useful for preparing metal material coated with graphene. ADVANTAGE - The method is simple and efficient, continuous and stable, flexible preparation type, greatly reducing the graphene difficulty of the metal material, easy to realize large scale production, and has no impurity and harmful substance, and the graphene diameter of the coated metal material is controllable, the purity is high, it solves the problem that the prior art preparation difficulty is high. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for preparation system of metal material coated with graphene.
