Abstract

A new silver-based electrocontact material dispersion-strengthened with nanopowders of zinc, tin, and titanium oxides has been obtained. The microstructure and elemental composition of the phases formed during solid-phase sintering and electroerosive tests have been studied by electron microscopy and energy-dispersive microanalysis. The electroerosive wear is determined during laboratory tests, and the transition resistance is calculated. The developed electrocontact material possesses physicomechanical and operating characteristics that are similar to those of a commercial contact prepared using toxic cadmium oxide.

分散了锌,锡和钛氧化物的银基电接触材料

摘要

已经获得了分散有锌,锡和钛氧化物纳米粉的新型银基电接触材料。固相烧结和电腐蚀试验中形成的相的微观结构和元素组成已通过电子显微镜和能量分散显微分析进行了研究。在实验室测试期间确定电腐蚀磨损,并计算过渡电阻。所开发的电接触材料具有类似于使用有毒氧化镉制备的商业接触的物理机械和操作特性。
