Abstract not available for EP0262005
Abstract of corresponding document: US4803395
This process consists in introducing a copper slug (5) into a nickel cup (1), extruding the cup-and-slug assembly and shaping it to produce a bimetallic electrode. It is characterized in that before the introduction of the said copper slug into the cup, a platinum point (2) is fixed onto the nickel cup (1). The invention applies to electrodes for electrical ignition plugs for heat engines.
