Microstructure and properties of Ag/SnO2 functional material manufactured by selective laser melting

Microstructure and properties of Ag/SnO2 functional material manufactured by selective laser melting

Ag/SnO2, as a promising and environment-friendly electrical contact material, is widely applied in low-voltage apparatus. But the properties of Ag/SnO2 composites is difficult to improve due to the poor distribution phases and difficult component design. In this work, the Ag/SnO2 composites are prep...
