【発明の詳細な説明】
本発明は、貴金属によるガラス繊維用ブツシン
グに関する。DETAILED DESCRIPTION OF THE INVENTION The present invention relates to bushings for glass fibers made of precious metals.
通常、ガラス繊維用ブツシングは白金又は白金
系合金が材料として用いられ、高温における化学
的安定性を有していることがその理由であるが、
上記の材料は鋳造時にピンホールやブローホール
が発生し易く、これ等の内部欠陥を無くすことは
極めて困難であり、また製品を高温で使用してい
ると、結晶粒が粗大化し、自重や他の物質の重量
を受けて徐々に変形するが、このときピンホール
やブローホール等の内部欠陥に応力が伝わり、マ
イクロクラツクの発生を生じさせ、時間の経過と
共に遂には割れにまで発展することとなる。 Usually, glass fiber bushings are made of platinum or a platinum-based alloy, which is chemically stable at high temperatures.
The above materials are prone to pinholes and blowholes during casting, and it is extremely difficult to eliminate these internal defects.Furthermore, when the product is used at high temperatures, the crystal grains become coarser, causing weight loss and other problems. The material gradually deforms due to the weight of the material, but at this time stress is transmitted to internal defects such as pinholes and blowholes, causing microcracks that eventually develop into cracks over time. becomes.
そこで、本発明は上記の欠点を解決することを
目的とし、薄い板状にしたPt、Pt−Au、Pt−
Rh、Pt−Irを単独または二種以上複数枚重ねて
一体にした材料によつて製造することを特徴とす
る。 Therefore, the present invention aims to solve the above-mentioned drawbacks, and aims to solve the above-mentioned drawbacks.
It is characterized by being manufactured from a material made of Rh, Pt-Ir alone or by stacking two or more of them.
以下に本発明の一実施例を説明すると、Pt、
Pt−Au、Pt−Rh、Pt−Irインゴツトを熱間鍛造
し、圧延を行なつて薄い材料とする。この様にし
たPt及びPt合金材料の単独または二種以上の材
料を所望枚数重ね合せて熱間圧着を行なつて希望
寸法の形状に加工して製作するものである。 One embodiment of the present invention will be described below. Pt,
Pt-Au, Pt-Rh, and Pt-Ir ingots are hot forged and rolled into thin materials. A desired number of Pt and Pt alloy materials, or two or more of them, are superimposed and hot-pressed to form a shape with desired dimensions.
尚、Pt−Auは好ましくはPt−１〜10％Au、Pt
−Rhは好ましくはPt−５〜20％Rh、Pt−Irは好
ましくはPt−５〜35％Irの割合が良い。 In addition, Pt-Au is preferably Pt-1 to 10% Au, Pt
-Rh is preferably Pt-5 to 20% Rh, and Pt-Ir is preferably Pt-5 to 35% Ir.
以上の本発明によるガラス繊維用ブツシング
は、機械的強度が従来品より増大し、特に高温耐
久性は著しく向上する。 The above bushing for glass fiber according to the present invention has increased mechanical strength compared to conventional products, and in particular, high temperature durability is significantly improved.
この理由は、材料の鋳造時に吸蔵ガスを放出し
ながら固化収縮するが、この冷却過程における収
縮や放出ガスによつて生ずる収縮孔、ピンホール
やブローホール等の欠陥がインゴツト内に不規則
に散在し、一般的鋳造法ではこれら内部欠陥を完
全に排除することは不可能と云える。また、これ
ら内部欠陥は発生機構上局部に集中する傾向があ
るため、そこに応力が加わつたり、腐食性物質と
接触した場合、割れや腐食物に発展する。 The reason for this is that when the material is cast, it solidifies and shrinks while releasing occluded gas, but defects such as shrinkage holes, pinholes, and blowholes, which are caused by the shrinkage and released gas during this cooling process, are irregularly scattered within the ingot. However, it is impossible to completely eliminate these internal defects using general casting methods. Furthermore, because these internal defects tend to concentrate in localized areas due to their mechanism of occurrence, if stress is applied to them or if they come into contact with corrosive substances, they will develop into cracks or corrosive substances.
本発明は上述の如くこれら内部欠陥が存在する
インゴツトを薄くし多数枚重ねて複合することに
よつて各層の集中欠陥を分散せしめ、その結果と
して割れや腐食が後続の層によつて喰い止められ
ることとなる。 As mentioned above, the present invention disperses the concentrated defects in each layer by thinning the ingots containing these internal defects and stacking them in large numbers, thereby preventing cracks and corrosion from occurring in the subsequent layers. It happens.
更に本発明による材料を再結晶温度以上で使用
した場合、結晶の成長は各層間で抑制される為、
全体が微結晶質となり、高温強度が著しく向上す
るものである。 Furthermore, when the material according to the present invention is used at a temperature higher than the recrystallization temperature, crystal growth is suppressed between each layer.
The whole becomes microcrystalline, and the high temperature strength is significantly improved.
以上の様な理由によつて本発明によるガラス繊
維用ブツシングは、耐久性、機械的強度にすぐれ
た性質を有するものである。 For the above reasons, the glass fiber bushing according to the present invention has excellent durability and mechanical strength.
