| Abstract: |
| Cu@Ag coated powder was prepared by electroless plating and sintered by spark plasma sintering technology (SPS). The scanning electron microscope and transmission electron microscope were used to study the microstructure of the coated powder and sintered samples. The phases and densities of the samples were characterized. The results showed that there is obvious coating on the surface of Cu@Ag powder prepared by electroless plating. By using SPS, a high-density Cu-Ag sintered block can be obtained. At 550 ° C, the density reached a maximum of 96.76%. At low temperatures, the necking of nano-silver promotes the sintering; at high temperatures, solid solution between Cu and Ag promotes sintering. |
