METHOD FOR COMPOUNDING CARBON NANO MATERIAL AND MAGNESIUM-BASED ALLOY

摘要

PROBLEM TO BE SOLVED: To prevent the intrusion of impurities into a melt when the stirring/mixing of a magnesium-based alloy and a carbon nano material is performed in an anticombustion gas atmosphere by the adoption of a shielding cover.

SOLUTION: The stirring/mixing of a magnesium-based alloy melted in a sealed melting vessel and a carbon nano material is performed in an anticombustion gas (SF6) atmosphere. The boundary between the magnesium-based alloy and the anticombustion gas atmosphere is provided with a shielding cover in contact with a melting face. The production of a compound between the anticombustion gas and magnesium is suppressed so as to prevent its intrusion into the melt caused by the stirring by the shielding cover. The carbon nano material and the magnesium-based alloy are compounded.
