USE - Metallurgical material for valve (claimed). ADVANTAGE - The metallurgical material increases wear resistance, toughness and heat resistance of the valve. DETAILED DESCRIPTION - Metallurgical material comprises 1-2 pts. wt. molybdenum powder, 2-3 pts. wt. titanium powder, 0.2-0.3 pts. wt. niobium, 10-12 pts. wt. tantalum carbide, 2-3 pts. wt. tantalum, 3-5 pts. wt. zirconium, 0.3-0.4 pts. wt. graphene, 0.1-0.2 pts. wt. phophorus, 0.3-0.4 pts. wt. silane coupling agent KH-550, 2.5-3.5 pts. wt. 1% sodium carbonate solution, 0.4-0.6 pts. wt. polyethylene glycol, 30-35 pts. wt. copper sulfate solution (2Mol/L), 2-3 pts. wt. wetting agent and 70-74 pts. wt. iron powder. The wetting agent comprises 0.1-0.2 pts. wt. strontium chloride, 0.2-0.4 pts. wt. phosphorus pentoxide, 0.4-0.6 pts. wt. polyethylene glycol, 2.3-2.8 pts. wt. potassium Hexafluorozirconate, l.3-1.6 pts. wt. molybdenum, 0.6-0.9 pts. wt. nanometer sodium stannate, 0.3-0.5 pts. wt. nanometer cerium(IV) oxide, 0.2-0.4 pts. wt. nanometer carbon, 0.6-0.9 pts. wt. aluminum powder, 0.1-0.2 pts. wt. sodium fluoride, 8-10 pts. wt. acetone and 0.1-0.2 pts. wt. polyethylene glycol 400. The wetting agent is prepared by mixing polyethylene glycol 400 and acetone, and then stirring the mixture uniformly. Rest components are added to mixture, and then stirred 8000-10000 revolutions per minute for 10-15 minutes. The mixture is ultrasonically dispersed, and then processed in presence of argon at 1300-1400 degrees C 20-30 minutes. The obtained material is cooled, and then crushed to obtain the finished product. An INDEPENDENT CLAIM is included for a method for preparing metallurgical material, which involves using molybdenum powder, titanium powder, niobium, tantalum carbide, tantalum, zirconium, graphene, phophorus, silane coupling agent KH-550, 1% sodium carbonate solution, polyethylene glycol, copper sulfate solution (2Mol/L), wetting agent and iron powder.
