Beschreibung
Zusammenfassung:	The present invention belongs to the technical field of metal matrix composites, disclosing a kind of Cu/C/SiC composite material and its preparation method, the preparation method is: SiC particles coated with SiO2-Cu2O interface modification phase on the surface are used as precursors, and they are uniformly mixed with Cu powder and graphite powder by ball milling to obtain composite powder; The composite powder is pre-pressed to obtain the green body; The microwave transmission material is evenly placed around the green body, and subsequently, the Cu/C/SiC composite material is obtained by microwave treatment at a temperature of 700~1000°C for 10~30min.The present invention adopts the introduction of graphite into Cu/SiC composite powder, so that in the process of microwave sintering, it can form microwave hot spots, accumulate heat, improve the diffusion rate of atomic interfaces, and can realize the rapid preparation of Cu/C/SiC composites at low temperatures.
