The Ag coating Cu bimetallic nano-powders were synthesized by substitution reaction with AgNO3.The synthesis process was discussed and the bimetallic powders were characterized by TEM, EDXS and XRD. The experimental results indicate that the bimetallic powders have a Ag coating Cu nano-powder structure and disperse well, the average grain size is 70 nm and the Ag molar content on the surfaces of the bimetallic powders reaches 74.28%. The oxidation of Cu nano-powders in the lavation process was avoided effective by adding of protective reagent.
