NOVELTY - The method involves determining the three-dimensional solid model of the wear-reducing metal material. The mixed powder is evenly spread on the working platform of the SLM equipment, the air in the forming chamber is evacuated, and the inert gas is filled. When the volume content of oxygen in the forming chamber is less than 0.1%, according to the program files imported into the SLM equipment and the forming process parameters, the SLM equipment is configured to begin to melt in the selected area, and after each layer of mixed powder is melted in the selected area. The working platform of the SLM equipment is reduced by one layer thickness, and then the next layer of mixed powder is laid, and the selected area continues to be melted. The process is repeated until the anti-friction metal material is stacked and formed. The anti-friction metal material formed is subjected to aging treatment to obtain a finished graphene composite 18Ni300 anti-friction metal material. USE - Method for preparing graphene composite 18Ni-300 anti-friction metal material based on SLM technology. ADVANTAGE - The method is configured to utilize selective laser melting technology to form graphene composite 18Ni-300 for reducing abrasion metal material, compared with the traditional mold pressing, the smelting method has simple preparation technique and is configured to provide excellent wear resistance, strong durability, and excellent abrading performance.
