Abstract
Using a plasma arc coating process or a thermospraying process or a detonation process an electrode of a rotor of a distributor for the ignition system of an internal combustion engine was surface treated to provide the electrode with a surface layer of an electrically high resistive material, e.g. CuO. A distributor having the treated rotor included therein exhibited significantly suppressed noise. Instead of or in addition to the rotor, each of the stationary terminals of the distributor may be so treated.
