Abstract
Disclosed is a method of coating electrodes in spark gap devices which minimizes filament formation. A coating (21) such as carbon is deposited on the electrode surfaces (11 and 12). A signal is then applied so that the device conducts in the arc mode for several short periods. A small spot of the coating bonds with the negatively biased electrode during each conduction. This operation continues at alternating polarities until essentially the entire surface area of both electrodes is bonded.
