▎ 摘　　要

NOVELTY - The method involves providing a metal material. The graphene coating is obtained by chemical vapor deposition growth on the surface of the metal material. The carbon source gas is selected from one or more of methane, ethane, ethylene, acetylene, methanol and ethanol, and the flow rate of the carbon source gas is 0.05sccm to 00sccm. The material of the metal material is pure metal or alloy. The elements contained in the metal material are selected from aluminum, beryllium, cadmium, cobalt, gold, hafnium, indium, iridium, iron, lead, molybdenum, nickel, platinum, palladium, rhenium, silver, tantalum, titanium, tungsten, vanadium, zinc, zirconium, bismuth, copper, manganese, magnesium, chromium, rhodium, ruthenium, and aluminum. USE - Method for preparing high infrared element (claimed) used in aerospace, industrial furnace, metallurgy manufacturing, and building coating field. ADVANTAGE - The method of growing the graphene infrared radiation enhanced coating on the metal material substrate is simple and effective, and is convenient to be extended to large-scale production. The infrared emission capability of metal materials are graphene effectively enhanced, so that the radiation temperature is greatly increased, and the graphene coating is tightly combined with the substrate and is not easy to fall off. DETAILED DESCRIPTION - INDEPENDENT CLAIMS are included for: (1) a high infrared element; and (2) a device for radio frequency plasma enhanced chemical vapor deposition on nickel chromium alloy fiber. DESCRIPTION OF DRAWING(S) - The drawing shows a scanning electron microscope image of the composite fiber.
