状態で用いられる電気接点材料の製造方法に関するもの
である。[Detailed Description of the Invention] The present invention is a composite material in which a silver-oxide alloy material (a material in which cadmium oxide, tin oxide, bismuth oxide, antimony oxide, zinc oxide, indium oxide, etc. are dispersed in the wire) is bonded to a composite material. The present invention relates to a method for manufacturing electrical contact materials used in the state of the art.

。In general, silver-oxide alloy materials have excellent electrical properties such as welding resistance, and are widely used as electrical contact materials in the medium current range. This silver-oxide alloy material is mainly used in actual use while being bonded to other composite materials, but its excellent welding resistance may be an obstacle when bonding with other composite materials. Therefore, sufficient bonding strength cannot be obtained.

ず電気接点として稼動中に銀−酸化物合金材料と銀層と
の境界から剥離して脱落するという欠点があった。Conventionally, when joining a silver-oxide alloy material to a composite material, a silver layer is provided between the silver-oxide alloy material and the composite material, and the silver-oxide alloy material is bonded to the composite material through this silver layer. Although the bonding strength was still insufficient, there was a drawback that the silver-oxide alloy material and the silver layer would peel off from the boundary between the silver-oxide alloy material and the silver layer during operation as an electrical contact. .
本発明は、上述した様な諸事情に鑑みて威されたもので
あり、銀−酸化物合金材料を合材に接合した場合に於い
て充分なる接合強度の得られる電気接点材料の製造方法
を提供せんとするものである。The present invention was developed in view of the above-mentioned circumstances, and provides a method for manufacturing an electrical contact material that provides sufficient bonding strength when a silver-oxide alloy material is bonded to a composite material. This is what we intend to provide.
以下本発明より成る電気接点材料の製造方法について説

ある。The method for manufacturing the electrical contact material according to the present invention will be described below. When bonding the silver-oxide alloy material to the base material, the silver-oxide alloy material and the composite material are mixed with 0.01 to 2% by weight of phosphorus.
The silver-oxide alloy material and the composite material are heat-pressed or welded via the copper alloy containing the silver-oxide alloy material.
然るに、縁−酸化物合金材料が他の材料との接合性に劣
るのは、銀−酸化物合金材料表面の酸化物がその接合性

ものであり、銀−酸化物合金材料と台材の間にりんを含
有する銅合金を介在せしめることにより、観−酸化物合
金材料表面の酸化物が前記銅合金中のりんに還元され、
その結果接合強度を向上ならしむるものである。However, the reason why edge-oxide alloy materials have poor bonding properties with other materials is that oxides on the surface of silver-oxide alloy materials inhibit the bonding properties, and the present invention focuses on this point. By interposing a copper alloy containing phosphorus between the silver-oxide alloy material and the base material, the oxide on the surface of the silver-oxide alloy material is reduced to phosphorus in the copper alloy. is,
As a result, the bonding strength is improved.
尚、本発明に於いてりんの量を０，０１〜２重量％に限
定したのは、０．０１重量％以下では、銀−酸化物合金
材料表面の酸化物を還元する効果が薄く、充分なる接合
強度を得ることが出来ないからであり、又２重量％以上
では、りんの作用で材料が脆くなり、接合面に割れが発
生してしまうからである。The reason why the amount of phosphorus is limited to 0.01 to 2% by weight in the present invention is that if it is less than 0.01% by weight, the effect of reducing oxides on the surface of the silver-oxide alloy material is weak, and it is not sufficient. This is because it is not possible to obtain a bonding strength of 2% by weight or more, and the material becomes brittle due to the action of phosphorus and cracks occur on the bonding surface.
次に本発明を更に明瞭ならしむるべく、その具体的な実
施例及び従来例について説明する。Next, in order to further clarify the present invention, specific embodiments and conventional examples thereof will be described.
