合金内氧化AgCuO电接触材料的组织和性能研究
|
摘要
采用内氧化法生产不同成分的AgCuO(10)电接触材料,研究添加微量Ni、稀土和Sn对AgCuO(10)组织形貌、机械物理性能和电接触性能的影响,结果表明,添加元素均能起到细化氧化物颗粒的作用,其中Sn的作用最为明显;不同成分的AgCuO(10)材料均具备良好的冷加工性;Sn的添加能极大程度的提高AgCuO(10)的抗熔焊性能。
Different AgCuO(10) electrical contact materials were produced by internal oxidation method. The effects of adding Ni, rare earth and Sn on AgCuO(10) tissue morphology, mechanical physical properties and electrical life were studied. The results show that, the additives all can be used to refine the oxide particles, of which Sn has the most obvious effect; the AgCuO(10) materials with different components all have good cold processability; the addition of Sn can greatly improve the welding performance of AgCuO(10).
