NOVELTY - Composite modifier is composed of 1-2 pts. wt. vanadium boride, 1-2 pts. wt. graphene oxide, 1-3 pts. wt. molybdenum powder, 1-2 pts. wt. niobium powder, 3-4 pts. wt. nickel powder, 0.2-0.3 pts. wt. metal porphyrin, 1-2 pts. wt. sodium fluoride, 1-2 pts. wt. fluorite powder, 1-2 pts. wt. ceramic nanopowder, 3-4 pts. wt. multi-walled carbon nanotube, 5-8 pts. wt. calcium-silicon alloy powder, 25-30 pts. wt. 10-12% ethanol solution, 1-2 pts. wt. magnesium dihydrogen phosphate and 0.5-1 pts. wt. auxiliary agent. USE - Composite modifier for heat-resistant cast iron or molybdenum-niobium, nickel-silicon calcium alloy. ADVANTAGE - Heat-resistance is improved, thus providing thermal stability. DETAILED DESCRIPTION - Composite modifier is composed of 1-2 pts. wt. vanadium boride, 1-2 pts. wt. graphene oxide, 1-3 pts. wt. molybdenum powder, 1-2 pts. wt. niobium powder, 3-4 pts. wt. nickel powder, 0.2-0.3 pts. wt. metal porphyrin, 1-2 pts. wt. sodium fluoride, 1-2 pts. wt. fluorite powder, 1-2 pts. wt. ceramic nanopowder, 3-4 pts. wt. multi-walled carbon nanotube, 5-8 pts. wt. calcium-silicon alloy powder, 25-30 pts. wt. 10-12% ethanol solution, 1-2 pts. wt. magnesium dihydrogen phosphate and 0.5-1 pts. wt. auxiliary agent. The latter contains 2-3 pts. wt. stainless steel fiber, 4-5 pts. wt. silicon strontium nucleating agent, 3-5 pts. wt. 20-30% quenching liquid, 0.5-0.8 pts. wt. sodium lignosulfonate, 1-3 pts. wt. manganese oxide, 0.8-1 pts. wt. calcium metaborate, 2-3 pts. wt. organic bentonite and 12-15 water. Preparation involves dissolving sodium lignin sulfonate and calcium metaborate in water, adding organic bentonite, stirring and mixing for 20-30 minutes and grinding for 1-2 hours.
