After this, SEM was used to observe and compare the surface appearance of the rivets. The mechanism of the effects of the additives on the electrical properties of AgNi(10) contact material was analyzed.

• 将含不同添加物的AgNi(10)线材分别加工成平面、球面复合铆钉型触头,并配对装配于ASTM标准试验机上进行电性能模拟试验,得出了含不同添加物的AgNi(10)线材的电磨损及接触电阻数据,并利用扫描电镜对电性能模拟试验后的触头表面形貌进行了对比观察,在此基础上初步分析了不同类型的添加物对AgNi(10)材料电性能的影响机理。
