Abstract
A process for fixing a graphite-rich material onto a metallic body by mixing graphite powder with a plastic material to obtain a graphite-rich material, pressing the graphite-rich material onto a layer of a metal-rich material, in a single step, forming thereby a green pressing formed of a graphite-rich component and a metal-rich layer, aligning the green pressing with the metallic body to which it is to be fixed, and subjecting the aligned metallic body and green pressing to a heat treatment to bond the metal-rich layer to the metallic body.
