▎ 摘　　要

NOVELTY - Method for preparing graphene nanosheet/amorphous iron-based composite coating, involves (i) preparing graphene nanosheet/amorphous iron-based alloy composite powder for plasma spraying, (ii) degreasing, decontaminating, ultrasonically cleaning, drying, and sandblasting the surface of the substrate before spraying and (iii) using 9 MB plasma spray gun to melt the composite powder prepared in the step (i) using plasma spraying and depositing on the pretreatment of obtained in the step (ii) and installing on the surface of the substrate above the rotary table to obtain the product. USE - Method for preparing graphene nanosheet/amorphous iron-based composite coating. ADVANTAGE - The method has low porosity, high hardness, excellent wear resistance and corrosion resistance, and excellent mechanical properties and greatly improves market competitiveness.
