Abstract

Abstract A method of forming a nitride ceramic-metal complex material without using a special bonding material. This method comprises bringing a metallic material into contact with the surface of a nitride ceramic material, heating under vacuum the nitride ceramic material so as to dissociate the surface of the nitride ceramic material into nitrogen and a precursor of the ceramic material, thereby allowing the dissociated precursor to react with the metallic material and to achieve bonding between the nitride ceramic material and the metallic material. A nitride ceramic-metal complex material produced by the above method is also proposed.

Claims Analysis

Total Claims: 9
Claim 1
Independent Claim 117 words
A method of producing a nitride ceramic-metal complex material, which is characterized in comprising the steps of: bringing a metallic material selected from the group consisting of a metal rich in reactivity with a precursor to nitride and an alloy of said metal into contact with the surface of a nitride ceramic material; and heating under vacuum the nitride ceramic material which is kept in contact with the metallic material so as to dissociate the surface of the nitride ceramic material into nitrogen and a precursor to nitride, thereby allowing the dissociated precursor to nitride to react with the metal or alloy thereof so as to achieve bonding between the nitride ceramic material and the metallic material.
