電気接点材料としてＡｇ、Ａｇ−ＮｉあるいはＡｇ中に
Ｃｄ、Ｓｂ、Ｓｎ、Ｉｎ、Ｚｎ等の酸化物を分散させた
所謂Ａｇ−酸化物系材料が用いられている。As electrical contact materials, Ag, Ag-Ni, or so-called Ag-oxide materials in which oxides such as Cd, Sb, Sn, In, and Zn are dispersed in Ag are used.
特に、このＡｇ−酸化物系材料は耐溶着性、耐消耗性等
の接点特性が優れているために主に中負荷領域で使用さ
れているもので、接点の裏面にはＡｇ層を設けて合材に
ろう付けあるいはスポット溶接を行って固着する方法が
一般的にとられている。In particular, this Ag-oxide material has excellent contact properties such as welding resistance and abrasion resistance, so it is mainly used in medium load areas, and an Ag layer is provided on the back side of the contact. The commonly used method is to braze or spot weld the composite material.
ところが、近時工程の合理化を目的としてＡｇ−酸化物
系材料とＣｕあるいはＣｕ合金の条材を複合した複合材
料が多く用いられるようになってきた。この複合材料は
Ａｇ−酸化物系材料とＣｕあるいはＣｕ合金の直接の接
合が困難であるために、通常は中間層としてＡｇ層を介
在させて製造している。However, in recent years, composite materials made of Ag-oxide materials and Cu or Cu alloy strips have come into widespread use for the purpose of streamlining processes. Since it is difficult to directly bond the Ag-oxide material and Cu or Cu alloy, this composite material is usually manufactured with an Ag layer interposed as an intermediate layer.
以上のようなＡｇ−酸化物系材料とＣｕあるいはＣｕ合
金の条材を複合した複合材料は、ＣｕあるいはＣｕ合金
とＡｇとの接合強度には問題はないが、Ａｇ−酸化物系
材料とＡｇ層間では充分な強度が得られないという問題
がある。Composite materials such as those made by combining Ag-oxide-based materials and Cu or Cu alloy strips have no problem with the bonding strength between Cu or Cu alloy and Ag, but the bonding strength between Ag-oxide-based materials and Ag There is a problem that sufficient strength cannot be obtained between the layers.
接点開閉後の接点を観察すると、特に接点端部において
、ＡｇとＡｇ−酸化物系材料との接合界面に微細なりラ
ンクが発生する。この発生したクラックはさらに接合界
面内部へと徐々に進行し、やがて接点剥離となるという
可能性がある。When observing the contact after the contact is opened and closed, fine ranks appear at the bonding interface between Ag and the Ag-oxide material, especially at the end of the contact. There is a possibility that this generated crack will further progress gradually into the inside of the bonding interface, and eventually lead to contact separation.
また、これらのクラックは接点開閉時に発生するジュー
ル熱やアーク熱等の熱拡散の悪化を助長し、接点の疑似
溶着や異常消耗の原因となる問題がある。In addition, these cracks promote the deterioration of heat diffusion such as Joule heat and arc heat generated when the contacts are opened and closed, causing false welding and abnormal wear of the contacts.
本発明は、Ａｇ−酸化物系材料に対して接合性が良好で
ある未酸化組成Ａｇ合金即ち、Ａｇ−酸化物系材料と同
