METHOD FOR SURFACE TREATMENT OF ELECTRODE IN DISTRIBUTOR OF INTERNAL COMBUSTION ENGINE FOR SUPPRESSING NOISE ABSTRACT OF THE DISCLOSURE An electrode for a spark discharge in a distributor is surface treated by using a spray coating process so as to provide the electrode with a surface layer of an electri- cally high resistive material, e.g. CuO, which surface layer further includes a predetermined percentage of refractory and electrical insulating material, e.g. A1203, SiO2 or MgO?A1203. A distributor having one such treated electrode for the distributor rotor and/or such treated electrodes for stationary terminals can exhibit stably-suppressed noise for over a long period of time. - 1 -
