| Abstract |
| Contact materials are used in many electrical devices. Ag-Cd alloy has been widely used in electrical part, because Ag-Cd alloy has a good wear resistance and stable contact resistance. But nowadays Ag-Cd alloy isn`t being used because of environmental challenges. Currently new research is being done on (Ag-SnO2 and Ag-SnO2-In2O3) as an alternative solution to fix any remainly environmental challenges. However In2O3 is more expensive and Ag-Sn alloy has low wear resistance. According to our research data Zn has a similar physical and chemical property. In this work, so we changed and optimized the Zn oxide to over 4 and added Sn oxide ratio 0.5, 1.0, 1.5wt%. Conclusions from the data recorded from the experiment of Ag-ZnO-SnO2 are as follows. |
