| 摘 要： | 本工作研究了添加元素Te、In、Sn、Al和Ni对内氧化Ag-4-8.5wt％Zn合金组织和性能的影响。少量Te或Te、In、Sn均能改善合金组织状态,使合金中氧化物呈粒状而且分布均匀;Al、Ni则不能改变这类合金中氧化物的针状特征。结果指出,添加适当的元素和控制ZnO含量能获得高抗熔焊性、高抗腐蚀性和低的接触电阻等开关特性优异的触头材料。

| Abstract: | The effect of additional some elements on the structure and electric properties of internal oxidized Ag-4-8.5 wt% Zn alloys has been investis gated.Three kinds of experiments has been done, e . g . ( 1 ) adding Te, Al, and Ni; ( 2 ) adding Te, In and Sn; ( 3 ) adding Al and Ni. Both cases (1 )and( 2 )have shown the improvement of the structure of oxides, but the case ( 3 ) has not.The results indicate that adding a small amount of available lements and controlling the content of ZnO can improve the such performance of switch in electric contact materials as to gain high resistance to welding adhesion, high resistance to erosion and low contact resis-etance. |
