This letter presents the results of Auger analysis of surface products by steady arc on Ag/Pd contacts. Black products formed on Ag contact surfaces, which make contact resistance high and unstable, are silver oxide. In the case of Pd contacts, contact resistance of which remains low and stable, white-colored products seen after operations seem to be powdery palladium.
