ABSTRACT:
An intermetallic bond between a ferrous metal and a non-ferrous metal wherein an intermetallic bond layer that is substantially free of graphic inclusions joins the two. The graphite is effectively eliminated from the bond layer by either removing it from the ferrous metal or by sealing it off from the bond layer. Graphite removal may be accomplished in a variety of ways, including electrochemical cleaning and laser surface treatment. Alternatively, the graphite may be prevented from incursing into the bond region by sealing it off with a layer of metal, such as a chromium plating, that prevents it from penetrating through the bond layer and into the non-ferrous metal.
