| Abstract(in English) | Ag, Pd, and Cu contacts were operated in air and nitrogen atmosphere to break an inductive DC load current of 0.5 to 3 A. Ag contacts in air and nitrogen, as well as Pd contacts in air, showed the anode-gain and cathode-loss characteristics. Pd contacts in nitrogen were likely to show the pip-formation on cathodes and the crater-formation on anodes. For Cu contacts, differences of the resultant anode profiles were observed between the air samples and the nitrogen samples. Moreover, the pip/grater volumes measured with a scanning laser microscope showed some different tendencies as compared to the mass change characteristics. |
