Abstract
Sposób wytwarzania kompozytów magnezowych z pianami węglowymi polega na tym, że otwartokomórkowe piany węglowe amorficzne zawierające pory o średnicy 250 - 1200 µm umieszcza się w formie, korzystnie grafitowej, a następnie wypełnia ziarnami proszku czystego technicznie magnezu lub jego stopów odlewniczych średnicy nie większej niż 300 µm i mniejszej niż 35% średnicy otworów komórki piany i zagęszcza na sucho, poddając drganiom pionowo - skrętnym o częstotliwości 50 Hz w kilku cyklach, korzystnie trzech uzupełniając proszek magnezu tak, aby po zakończeniu zagęszczania na górnej powierzchni kształtki pozostał naddatek, korzystnie warstwa proszku o grubości nie mniejszej niż 20% jej wysokości, po czym całość ogrzewa się w próżni lub atmosferze ochronnej do stopienia metalu, prasuje i chłodzi pod obciążeniem.The method of producing magnesium composites with carbon foams consists in the fact that amorphous open-cell carbon foams containing pores with a diameter of 250 - 1200 µm are placed in a mold, preferably graphite, and then filled with grains of technically pure magnesium powder or its casting alloys not larger than 300 µm in diameter and smaller than 35% of the diameter of the holes of the foam cell and compacted dry, subjecting vertically to torsional vibrations with a frequency of 50 Hz in several cycles, preferably three, supplementing magnesium powder so that after completing the compaction on the upper surface of the molded piece an excess, preferably a layer of powder not less than 20% of its height, after which the whole is heated in a vacuum or protective atmosphere until the metal melts, pressed and cooled under load.
