The invention relates to the field of composite materials, in particular to a method for preparing diamond composite materials. The diamond powder is sequentially subjected to pretreatment, surface etching, and nickel plating to obtain nickel-plated diamond powder, which is mixed with titanium powder, silicon powder, titanium carbide powder, and copper powder. The powders are fully mixed and sintered by plasma. The diamond composite material of the present invention has high density, good thermal conductivity, excellent bending strength, hardness and impact toughness. |
