Abstract
The method for bonding graphite to metal, includes the steps of forming a metal carbide layer on a surface of the graphite, the metal being to be bonded to said graphite, and brazing the graphite to the metal with an active alloy brazing material. The present invention is based on the fact discovered by the inventor that if a metal carbide layer is in advance formed on a surface of a graphite, an active metal such as Ti could more easily react on the metal carbide layer to thereby bond the metal to the graphite, rather than the case in which a graphite member is made to directly react on an active metal to thereby bond the graphite member to the metal.
