METHOD FOR OBTAINING OF NANOSIZED POWDERS OF ALUMINIUM-SILICON ALLOYS

摘要

FIELD: metallurgy.;SUBSTANCE: initial material consists of mixture of powders of aluminum silicate, crystals and dolomite at their weight ratio equal to 1: 0,06-0,45 : 0.08-0.24, supplied by flow of plasma-forming gas to reactor of gas-discharge plasma at temperature in reactor equal to 5000-6000°C, products of thermal decomposition: are cooled by inert gas and obtained powder of aluminium-silicon alloy is condensed in water-cooling receiving chamber.;EFFECT: invention allows obtainment of nanosized powders of aluminium-silicon alloys with alloy additives of calcium and magnesium thus conferring ductility and corrosive resistance to products made from these powders.;4 cl, 6 ex
