Abstract:
A method for making a gasket (32) for an internal combustion engine (20) includes forming a generally annual stopper (38) on a metallic gasket body (40) through the process of electrochemical deposition. An electrolytic cell is completed with the gasket body (40) forming a cathode. The stopper (38) is formed with a contoured compression surface (42) by selectively varying the electrical energy delivered to selected electrodes (70) over time. Electrolyte (48) rich with metallic ions is pumped at high speed through the inter-electrode gap. A PC controller (82) switches selected electrodes (70) ON at certain times, for certain durations, which cause metallic ions in the electrolyte (48) to reduce or deposit onto the gasket body (40), which are built in columns or layers into a three-dimensional formation approximating the target surface profile (106) for the compression surface (42). The subject method for building a three-dimensional formation can be applied to work parts other than cylinder head gaskets (32).
