METHOD FOR PRODUCING METAL-CERAMIC COMPOSITE MATERIAL WITH EMBEDDED HEATER

摘要

PROBLEM TO BE SOLVED: To provide a method for producing a metal-ceramic composite material by which even a curved sinuous heater can easily be embedded without leaving a gap or void. SOLUTION: In the method for producing a metal-ceramic composite material with an embedded heater, a preform having an internal space is formed using a ceramic powder or ceramic fibers being a reinforcing material, a heater is put in the space, a ceramic powder- or ceramic fibers-containing slurry is poured into the space 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.
