新型电接触材料Ag-金属导电陶瓷的制备与性能

Preparation and Performance of the Novel Electrical Contact Materials of Silver-Metal Oxides

本研究从一种新的角度寻找Ag -CdO的替代材料。采用粉末冶金方法制备出Ag-ABO3颗粒弥散强化材料 ,并对新材料的制备工艺和电接触性能进行了研究。实验结果显示 :新材料具有良好的电学和力学性能 。

The present research work is an attempt to find a substitute for Ag-CdO from a new point of view.The new composite materials of Ag-ABO 3 were prepared by the method of powder metallurgy.The preparing technique and performance of the composite were studied.The experimental results showed that the new materials had excellent electrical and mechanical properties.But the heterogeneity of microstructure has an influence on the homogeneity of the performance.
