NOVELTY - Use of graphene is claimed as protective material for high-iron suspension wire. USE - Graphene used as protective material for high-iron suspension wire (claimed), preventing corrosion and oxidation of high-iron suspension wire, and protecting high-iron suspension wire for prolonging the service life of the high-iron suspension wire of high-speed rail. ADVANTAGE - The graphene is super-hydrophobic, and has corrosion resistance. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for a method for preparing high-iron suspension wire with graphene coated on its outer surface, which involves: (A) taking the high-iron suspension wire, cleaning, drying, placing in the quartz tube of vacuum tube type high-temperature sintering furnace, and adding a certain amount of reaction substance; and (B) placing the quartz tube at chemical vapor deposition temperature, under a certain reaction pressure, keeping for a period of time, cooling to room temperature and then taking out to obtain the finished product.
