By developed small-capacity ASTM contact material testing and measuring systems, 45,000 continuous make-break tests are performed on eight kinds of symmetry pairing of Ag/SnO2 electrical contact materials which adopt different processing technologies of mixed powder and chemical or spray process, and add the different doping agents： of WO3, BiO3, CuO or In2O3 on the condition of DC14V, 10A and light load. Qualities, arc energies, welding forces, ances of Ag/SnO2 moving contact and static contact arc durations, contact temperatures and contact resistare measured equivalent Ag/SnO2 contact materials before and after the tests. The special pots surface profiles and the microstructures of eight kinds of Ag/ SnO2 contact materials are observed and measured by SEM and EDAX before and after the 45,000 continuous operating tests, and the effects on DC arc erosions of the Ag/SnO2 contact material with processing technologies and additives on the condition of relay are discussed.
