12. A method for producing an aluminum-diamond-based composite comprising an overall surface coated with a surface layer, the method comprising:
-
1) preparing diamond powder; 2) preparing at least one aluminum-containing material selected from ceramics containing aluminum and metal materials containing aluminum; 3) filling a cavity of a porous mold member with the diamond powder in a state where the aluminum-containing material is placed on top and bottom surfaces of a layer of the diamond powder and the layer of the diamond powder is further sandwiched by mold release plates from top and bottom sides; and
impregnating the diamond powder with the metal containing aluminum by a molten metal forging method to prepare an aluminum-diamond-based composite precursor having a flat plate shape comprising a surface layer containing 80% by volume or more of a metal containing aluminum on top and bottom surfaces of the precursor; and4) filling a cavity of a porous mold member with the precursor in a state where the aluminum-containing material is placed on all side surfaces of the precursor and mold release plates are placed on both top and bottom surfaces of the precursor; and
impregnating the precursor with the metal containing aluminum by a molten metal forging method to prepare an aluminum-diamond-based composite having a flat plate shape comprising a surface layer containing 80% by volume or more of a metal containing aluminum on all the side surfaces of the composite. - View Dependent Claims (13, 14, 15, 16, 17)
