COMPOSITE MATERIAL OF METAL AND CERAMIC AND ITS PRODUCTION

摘要

PURPOSE:To obtain a composite material of a metal and a ceramic material closely bonded with each other. CONSTITUTION:A polymer precursor is sintered on one surface of a sintered ceramic material having open pores to close the pore and form a dense surface. A dense ceramic material is bonded to the dense surface with a soldering material. A castable alloy such as an Al alloy is cast into the other porous surface and solidified to obtain a composite material of a metal and a ceramic material closely bonded with each other. The metal and the ceramic material are firmly bonded together to form a composite material having high strength.
