Method for producing composite material and composite material produced thereby

Abstract

The present invention relates to a manufacturing method for a composite material comprising two or more metals or nonmetals and compounds thereof and, more particularly, to a manufacturing method in which a dispersion material can be dispersed very homogeneously into a base material of the composite material independently of the composition of the composite material. The present invention is characterized in that in a manufacturing method for a composite material in which a metal or a nonmetal or a compound thereof is used as abase material, and at least one kind of metals or nonmetals or compounds thereof different from the base material is dispersed as a dispersion material, a raw material for base material comprising a metal or a nonmetal or a compound thereof constituting the base material and at least one raw material for dispersion material comprising metals or nonmetals or compounds thereof constituting the dispersion material are evaporated simultaneously or alternately, and the evaporated particles are deposited on a substrate to form a bulk body.

1 . A manufacturing method for a composite material in which a metal or a nonmetal or a compound thereof is used as a base material, and at least one kind of metals or nonmetals or compounds thereof different from the base material is dispersed as a dispersion material, characterized in that 
 a raw material for base material comprising a metal or a nonmetal or a compound thereof constituting the base material and at least one raw material for dispersion material comprising metals or nonmetals or compounds thereof constituting the dispersion material are evaporated simultaneously or alternately, and the evaporated particles are deposited on a substrate to form a bulk body.    
     
     
         2 . A manufacturing method for a composite material in which a metal or a nonmetal or a compound thereof is used as a base material, and at least one kind of metals or nonmetals or compounds thereof different from the base material is dispersed as a dispersion material, characterized in that 
 a raw material for evaporation comprising a metal or a nonmetal or a compound thereof constituting the base material or a metal or a nonmetal or a compound thereof constituting the dispersion material is evaporated in an atmosphere of any one of hydrocarbon gas, oxygen gas, and nitrogen gas, and the evaporated particles are deposited on a substrate to form a bulk body.    
     
     
         3 . A manufacturing method for a composite material in which a bulk body manufactured by the method according to  claim 1  or  2  and a raw material for base material comprising a metal or a nonmetal or a compound thereof constituting the base material are melted, mixed, and formed by casting, by which the concentration of dispersion material is controlled.  
     
     
         4 . A manufacturing method for a composite material in which a composite material manufactured by the method according to any one of  claims 1  to  3  is rolled or heat-treated, by which the crystal structure is controlled.  
     
     
         5 . The manufacturing method for a composite material according to any one of  claims 1  to  4 , characterized in that a raw material is evaporated by a sputtering method.  
     
     
         6 . The manufacturing method for a composite material according to any one of  claims 1  to  5 , characterized in that the evaporated particles are deposited while the substrate is rotated.  
     
     
         7 . The manufacturing method for a composite material according to any one of  claims 1  to  6 , characterized in that the substrate has the same material as those of the base material.  
     
     
         8 . A composite material manufactured by the method according to any one of  claims 1  to  7 .  
     
     
         9 . The composite material according to  claim 8 , characterized in that the base material is aluminum and the dispersion material is carbon.
