▎ 摘　　要

NOVELTY - Preparing nickel-coated graphene silicon carbide involves using intermediate frequency furnace to melt the metal nickel, and using breeze to blow the nano-graphene into a vacuum tube with a diameter of 1m and a length of 27m, pouring the molten nickel water into the high-speed tuyere, blowing nickel water into the vacuum tube at a wind speed of 46m/s per second, and moving nano-graphene in a high-speed linear motion in the vacuum tube. The metal nickel particles are hit the graphene particles at a super speed, fully coating the graphene, and passing nitrogen into the vacuum tube to prevent oxidation of the nickel-coated graphene particles. The nickel sulfate, sodium hypophosphite, lactic acid, succinic acid, malic acid, citric acid, and potassium iodate are mixed under certain conditions to prepare a plating solution. USE - Method for preparing nickel-coated graphene silicon carbide. ADVANTAGE - The nickel-coated graphene silicon carbide is resistant to high temperature, corrosion resistance, toughness, and stability, and improves the service life of the graphene coating. DETAILED DESCRIPTION - Preparing nickel-coated graphene silicon carbide involves using intermediate frequency furnace to melt the metal nickel, and using breeze to blow the nano-graphene into a vacuum tube with a diameter of 1m and a length of 27m, pouring the molten nickel water into the high-speed tuyere, blowing nickel water into the vacuum tube at a wind speed of 46m/s per second, and moving nano-graphene in a high-speed linear motion in the vacuum tube. The metal nickel particles are hit the graphene particles at a super speed, fully coating the graphene, and passing nitrogen into the vacuum tube to prevent oxidation of the nickel-coated graphene particles. The nickel sulfate, sodium hypophosphite, lactic acid, succinic acid, malic acid, citric acid, and potassium iodate are mixed under certain conditions to prepare a plating solution. The nano silicon carbide particles are placed in nitric acid with a concentration of 70%, oscillated with ultrasonic waves, and then roughened for 30 minutes, taken out and rinsed with deionized water to obtain clean and rough surface nano silicon carbide particles. The nickel-coated graphene is mixed with absolute ethanol and acetic acid, added the silicon carbide particles with rough surface and mixed, and vibrated ultrasonically for 30-60 minutes to make the material sol uniformly dispersed. The silicon carbide and nickel-coated graphene particle sol is uniformly dispersed into a drying oven at 300-350 degrees C for 2-3 hours, taken out and cooled, and put in the plating solution, stirred during the plating process at a stirring speed for 2 hours at about 300 revolution per minutes. The nickel-coated graphene silicon carbide solution is dried and dryied the filtered nickel-coated graphene silicon carbide at a temperature of 120-160 degrees C for 3-6 hours to obtain uniform nickel-coated graphene silicon carbide particles. The 50-90g of high temperature resistant organic resin is added to 40-50g of nickel-coated graphene silicon carbide, stirred until the mixture is uniform, and finally make a nickel-coated graphene silicon carbide coating.
