To provide a method for manufacturing a ceramics/metal composite material by which infiltration of aluminum alloy can be performed in a short time without causing an uninfiltrated part even in the case of a large-size thick- walled composite material.
The method for manufacturing the large-size thick-walled ceramics/metal composite material comprises steps of forming a large-size thick-walled preform composed of ceramic powder by a wet molding method, making holes in the preform, pouring slurry composed of Mg-powder-containing ceramic powder using a nonaqueous binder as a solvent into the holes, drying and solidifying the slurry to integrate it with the preform, and then infiltrating molten Mg-containing aluminum alloy into the integrated preform in a nitrogen atmosphere at 700-900°C under no pressure.
