  The morphology and properties of Ag-SnO2 composites by electroplating method were discussed.The morphology, physical properties and silver-to-stannic dioxide boning of Ag-SnO2 composites by electroplating method were researched.It was obtained that the Ag-SnO2 composites by electroplating method represent uniform silver-distribution leading to high hardness and acceptable conductivity.It was demonstrated that the materials involved had a favorable microstructure and the preparation was easily-handled, which illustrates that the application of electroplating process in Ag-SnO2 composites can be advanced obviously.
