【発明の詳細な説明】
「発明の目的」
本発明は焼結合金の製造法に係り、安定した強度および
耐食性と相手部材に対するなじめ性をもった焼結合金の
比較的簡易で的確な製造法を提供しようとするものであ
る。[Detailed Description of the Invention] "Object of the Invention" The present invention relates to a method for producing a sintered alloy, and provides a relatively simple and accurate method for producing a sintered alloy that has stable strength, corrosion resistance, and conformability to a mating member. This is what we are trying to provide.
(産業上の利用分野)
耐食性と強度性に優れ、しかも相手部材に対する適切な
なじみ性をもった焼結合金についての製造技術。(Industrial application field) Manufacturing technology for sintered alloys that have excellent corrosion resistance and strength, as well as appropriate compatibility with mating parts.
(従来の技術)
焼結合金としては従来から種々のものが提案されている
が、鉄系のものは強度的に優れているとしても相手部材
に対するなじみ性に劣り、一方銅系のものはこのなじみ
性か良好であっても強度的に不充分である。(Prior art) Various sintered alloys have been proposed in the past, but iron-based alloys have excellent strength but are inferior in compatibility with mating parts, while copper-based alloys have poor compatibility with mating parts. Even if the compatibility is good, the strength is insufficient.
そこでこれらの焼結合金における有利点を共に具備せし
むべく、特公昭3B−22103号公報のような技術も
発表されている。即ち銅粉と錫粉からなる圧粉成形体を
亜鉛蒸気中で焼結せしめ、表面にCu −Sn−Znの

食性および強度性をも改善せしめることができ、従って
軸受などに採用するに好ましい焼結合金製品を提供する
ことができる。Therefore, techniques such as Japanese Patent Publication No. 3B-22103 have been published in order to provide all of the advantages of these sintered alloys. That is, a powder compact made of copper powder and tin powder is sintered in zinc vapor to form a ternary alloy of Cu-Sn-Zn on the surface, which makes it difficult to form a mating member as a copper-based sintered alloy. It is possible to provide a sintered alloy product that not only has conformability but also has improved corrosion resistance and strength, and is therefore suitable for use in bearings and the like.
(発明が解決しようとする課題)
上記のようにCu −Sn−Znの3元合金によるもの
は耐食性や強度性をも改善し得るものと言えるが表面の
みであり、合金体全般がそうした3元合金で形成される
わけでないから安定した均一な特性をもった製品を得る
ことができない。(Problem to be solved by the invention) As mentioned above, it can be said that the Cu-Sn-Zn ternary alloy can improve corrosion resistance and strength, but only on the surface, and the entire alloy body does not have such ternary alloys. Since it is not made of an alloy, it is not possible to obtain a product with stable and uniform properties.
又焼結に当ってZn%気を発生、滲透せしめることが必
要であるからその7.n蒸気の濃度を適切に管理するこ
とが容易でなく、このZn蒸気濃度の管理如何で製品の
品質特性にばらつきが生ずる。In addition, it is necessary to generate and permeate Zn% gas during sintering, so 7. It is not easy to appropriately control the concentration of Zn vapor, and the quality characteristics of products vary depending on how the concentration of Zn vapor is managed.
更にこのZn蒸気濃度の管理が適切であっても基本的に
はZn分が外部から滲透したものであるから合金成分組
成が不均一となり安定したものとならない。Furthermore, even if the Zn vapor concentration is properly controlled, the Zn content basically seeps in from the outside, so the alloy composition becomes non-uniform and unstable.
更に圧粉体と亜鉛蒸気発生源とが各別に扱われるので作
業性に劣り、製造工程、特に焼結工程が煩雑であって、
Zn分のロスも不可避でコストアンプの原因となり、又
この点からも安定性に欠ける。Furthermore, since the green compact and the zinc vapor generation source are handled separately, workability is poor, and the manufacturing process, especially the sintering process, is complicated.
Loss due to Zn is also unavoidable and causes cost increase, and also from this point of view, stability is lacking.
