NOVELTY - The preparation of cast-in-situ growth graphene-reinforced copper composite material, involves (1) reducing surface of copper powder, (2) using methane gas as carbon source, carrying out radio frequency plasma enhanced chemical vapor deposition method to grow graphene on the surface of copper powder, (3) placing copper powder with graphene grown on the surface into vacuum arc melting furnace, and pumping vacuum to less than 5x10-3 Pa, passing high-purity nitrogen, controlling chamber pressure 1-10x10-1 Pa, and smelting sample by arc smelting method, controlling smelting voltage of 15-30 V, smelting current of 100-200 A, and the smelting time of 1-3 minutes, continuously stirring the liquid metal in the crucible by magnetic stirring method, and after smelting is completed, cooling to obtain bulk sample. USE - Preparation of cast-in-situ growth graphene-reinforced copper composite material used in civil and military applications. ADVANTAGE - By combining in-situ growth and casting methods, the method effectively solves the problem of poor dispersion of graphene in the copper matrix, and ensures low manufacturing cost, large process flexibility, and enables formation of complex shapes and large castings, and compared with pure copper, the prepared graphene copper-based composite material has significantly improved mechanical properties.
