中文摘要:
      在本文中,研究了添加剂的粒度和AgSnO2触头材料的性能之间的关系。Bi2O3、TiO2和CeO2被选作添加剂,并且四种粒度被选择,与此同时添加剂的比例通过润湿性试验获得。AgSnO2 触头材料通过粉末冶金法制备。对掺杂不同种类不同粒度的AgSnO2触头材料的物理和电接触性能进行了研究,结果表明三种添加剂(Bi2O3、TiO2和CeO2)的粒度对触头材料性能的影响趋势是一致的,并且细的添加剂颗粒有利于AgSnO2触头材料性能的改进。随着添加剂粒度的减小,AgSnO2触头材料的物理和电接触性能都得到了提高,并且添加剂的最佳粒径200nm。结果表明AgSnO2触头材料的性能可以通过选择添加剂的最佳粒度改进。

英文摘要:
      In this paper,the relationship between additive particle size and the properties of AgSnO2 contact materials was studied.Bi2O3,TiO2 and CeO2 were chosen as additives,and four kinds of particle sizes were selected.Meanwhile, the proportion of additives was selected through wetting ability tests.And AgSnO2 contact materials are prepared by powder metallurgy technology.The physical and electrical contact properties of AgSnO2 contact materials doped with different kinds and particle sizes additive were studied,the results showed that the influence of particle sizes of three additives(Bi2O3,TiO2 and CeO2) on the properties of AgSnO2 contact materials is consistent,and fine additive particle is beneficial for the improvement of the properties of AgSnO2 contact materials.With the decrease of additive particle size, the physical and electrical contact properties of AgSnO2 contact materials are improved,and the optimal particle size of additive is 200nm.The results indicate that the properties of AgSnO2 contact materials can be improved by selecting the optimal particle size of additive.
