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 p… Show more
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
