Method of laminating graphite sheets to a metal substrate

A method for bonding graphite sheets to a metallic substrate. The metallic substrate is provided with a coating of low melt metal which forms an intermetallic phase or zone at the interface between the substrate and coating. The coated substrate while in solidified condition is placed in a press between a pair of graphite sheets. Heat is applied to the substrate and graphite sheets while under pressure to a temperature slightly above the melting point of the substrate coating but below the temperature which will destroy the intermetallic interface. The substrate and graphite sheets are cooled while maintained under pressure in the press with the graphite sheets becoming firmly bonded to the metallic substrate by the resolidified metal coating.
