| Abstract: |
| Graphene is a two-dimensional material composed of hexagonal carbon atoms. Due to its unique physical, chemical and mechanical properties, graphene has been considered as an ideal reinforcement phase of metal materials. Researchers have prepared composite coatings of various metals and graphene. In this paper, the composite coatings of graphene and various materials are reviewed in detail, including the preparation method and processes of the composite coating, the dispersion of graphene and the effect of graphene on the properties of the coating. Preparation methods such as electrodeposition, electroless plating and electric brush plating can obtain uniform and dense composite coatings. The addition of graphene refines the grains of the coating and changes the microscopic morphology of the coating. When graphene is added as the second phase particles, the mechanical ultrasonic dispersion effect is poor. Generally, the graphene is dispersed by adding a surfactant and then combined with mechanical ultrasonic dispersion. Among the surfactants, the dispersion effect of the combination of anionic and cationic surfactants is better. In addition, another method to maintain the dynamic equilibrium of graphene concentration in solution has also achieved good results. The addition of graphene as the second phase particles enhances the thermal conductivity, electrical conductivity, wear resistance, hardness and corrosion resistance of the metal coating. Finally, the development trend of metal and graphene composite coatings are analyzed. |
