Abstract

The invention is directed to an improved method for producing a composite spark plug electrode 58. Initially, a cup (15, Fig. 2), is formed from a corrosion resistant first metal and is partially filled with a billet (20) to form a composite billet (22). The composite billet (22) is partially extruded to form an electrode blank (30, Fig. 4). A cup opening (39, Fig. 8) is formed in the end of the electrode blank which was formed from the open end of the cup (15). An end of a terminal wire 40 is positioned within the cup opening (39) and the electrode blank walls adjacent the cup opening (30) are deformed inwardly to interconnect the electrode blank 30 with the terminal wire 40. The method may be used to attach a wire to a solid electrode. <IMAGE> [GB2169527A]
