Method for mixing powdered metal and nanocarbon material, and method for manufacturing nanocarbon/metal composite material

Abstract

A manufacturing method is provided to be used in place of a conventional mechanical alloying method. A powdered metal and a nanocarbon material are placed in an empty metal mill vessel containing no balls, and a mixture in which the powdered metal is coated with this nanocarbon material is obtained by shaking in three dimensions.

1 . A method for mixing a powdered metal and a nanocarbon material, said method comprising the steps of: 
 preparing a ball mill, a specified amount of a powdered metal, and a specified amount of a nanocarbon material;    placing said powdered metal and nanocarbon material in the empty metal mill vessel containing no balls; and    obtaining a mixture in which said powdered metal is coated with the nanocarbon material by shaking said mill vessel in three dimensions using said ball mill.    
     
     
         2 . The method of  claim 1 , wherein the nanocarbon material prepared in said preparatory step comprises a nanocarbon material dispersed in advance by ultrasound.  
     
     
         3 . A method for manufacturing a nanocarbon/metal composite material, said method comprising the steps of: 
 preparing a ball mill, a specified amount of a powdered metal, and a specified amount of a nanocarbon material;    placing said powdered metal and nanocarbon material in the empty metal mill vessel containing no balls;    obtaining a mixture in which said powdered metal is coated with the nanocarbon material by shaking said mill vessel in three dimensions using said ball mill; and    molding and sintering said mixture to obtain a sintered body.    
     
     
         4 . The method of  claim 3 , wherein the nanocarbon material prepared in said preparatory step comprises a nanocarbon material dispersed in advance by ultrasound.
