Abstract:

In order to improve the machinability and electrical performance of the Ag electrical contact materials. A new kind of nano-Ag/SnO2-TiO2 electrical contact materials were prepared by liquid phase in-situ chemical route. The distribution state of elements titanium in copper and their effects on the microstructures and properties have been studied. The results of SEM show that SnO2-TiO2 powders are small, uniform and with no obvious phenomenon of reunion. At last, Ag/SnO2-TiO2 electrical contact materials were prepared by powder metallurgy method and electrical performance were done. Test results show that the electrical properties of Ag/SnO2-TiO2 are superior to the electrical properties of Ag/SnO2. Hence Ag/SnO2-TiO2 may become a new contact material which can replace Ag/SnO2.
