METHOD FOR PRODUCING METAL-CERAMIC COMPOSITE MATERIAL

摘要

PROBLEM TO BE SOLVED: To provide a method for producing a metal-ceramic composite material by which an aluminum alloy uninfiltrated part is not formed even when the shape of the composite material is large. SOLUTION: In the method for producing a metal-ceramic composite material, a preform having a hole is formed using a ceramic powder or ceramic fibers being a reinforcing material, a slurry of a ceramic powder or ceramic fibers containing Mg is filled into the hole and dried, and then molten aluminum or aluminum alloy as a matrix is infiltrated into the preform in an atmosphere of nitrogen under normal pressure.
