The Effect of the Zn contents on Rapidly Solidified Ag-Zn Electric Contact Materials

摘要

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-SnO_2 and Ag-SnO_2-In_2O_3) as an alternative solution to fix any remainly environmental challenges. However In_2O_3 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 percent. Conclusions from the data recorded from the experiment of Ag-ZnO-SnO_2 are as follows.
