Abstract

一种焊接趋势小、接触电阻低、用途广泛的银-铁材料,用作电触点材料。除了银以外,其中含有3~30%(重量)铁和一种或多种添加物:0.05~5 %(重量)锰、铜、锌、锑、氧化铋、氧化钼、氧化钨或氮化铬及必要时含0-2%铜、钽和/或锑。

Description

本发明涉及用作电触点的含有其它添加物的银-铁材料。
电触点材料的重要要求是高燃阻、低电极压力和低接触电阻,填充物依赖于负荷及切换电流类型所要求的外形而有不同。对于暴露于大气之中用于低压技术的开关装置,如Ag/Sn O2是特别适用于100~3000 的切换电流的,这是由于它具备高燃烧阻力,而且焊接安全。事实证明,复合材料Ag/Ni可成功地用于低负荷场合,与纯银相比,其燃烧阻力有所提高,而其接触电阻无实质性增加。
另一种常用的复合材料是Ag/W,其特征是它具有高阻燃性,如在空气中进行频繁的切换,会形成一种钨酸银薄层,因而使接触电阻增大。
日本专利申请79/148,109介绍了除了银以外尚含有铁、镍、铬和/或钴的电触点材料。尤其是Ag    10FeO复合体,呈现出高焊阻及良好的导电能力。
尽管如此,这种材料至今仍末得到广泛应用,这是因为在切换时所形成的薄层以及因此而产生的大量接触热。对于其它已知添加物如镍、铬和/或钴也会出现同样的情况。
因此,本发明的目的是寻求一种用于电触点的银-铁材料,这种材料焊接趋向低,具有尽可能低的接触电阻,因而接触热量少,使用寿命长,可适用于不同切换电流的多种场合。
本发明达到了这一目的。选用银-铁材料,其中含有3~30%(重量)的铁和占这种材料总重0.05~5%的一种或多种下列添加物:锰,铜,锌,梯,氧化铋,氧化钼,氧化钨和氮化铬,其余为银。
令人惊奇的是,这些材料降低了接触电阻进而降低所产生的接触热,但是不损害其焊接安全的特性。与Ag/Fe-90/10相比,在接触热方面的改进效果高达43%。这一改进是借助所形成的氧化铁层了所产生之有益效果达到的。不含有添加物的Ag/Fe-90/10,材料呈现连续的氧化层,而有了上述添加物会对这一氧化层产生影响,结果降低了接触电阻并有好的焊接安全性。
特别适用的是含3~20%(重量)的铁和占总重0.2~2%的一种或多种如Mn,Cu,Zn,Bi,Bi2O3,Mo O3WO3和/或CrN的添加物的材料。此外,事实证明,除了3~20%(重量)的铁外,在银中添加0.2~2%纯金属添加物或0.2~2%纯非金属添加物也取得了成功。
除了3~20%铁以外,其中尚含有0.2~2%诸如锰、铜、锌、锑、氧化铋、氧化钼或氧化钨的一种添加物、其余则为银的材料呈现了很好的特性。最好是除了3~20%铁以外,材料中含0.2~2%锌、以及根据需要含0~2%铜、钽和/或锑,其余为银,或者含0.2~2%氧化钼,其余为银。本发明材料还可含锗,氧化铜(CuO)或氧化锌(ZnO)。
由于铁不溶于银,所以这些材料无法通过熔炼法制备。可以采用粉末冶金法制备这些材料。为此,如所用的铁粉粒度不大于32μm是有益的这样会使铁粉均匀地分布于混合物中并与其它添加物相互 发生作用,从而在切换过程中很少产生薄层。
用如此制备的材料进行了电切换试验,除了在模型试验台上进行接触电阻试验外,还采用了标准接触器测定接触热。
试验结果示于下表中,它表明与已知材料Ag/FeO-90/10相比的本发明的材料在接触电阻和接触热方面的改进。
