Description
【発明の詳細な説明】 発明の名称 歯に適用するための合金 技術分野 本発明は、歯に適用する丸めの、特にセラミックが焼きつけられる合金としての 合金に関する。[Detailed description of the invention] name of invention Alloy for applying to teeth Technical field The present invention is suitable for rounding applied to teeth, especially as an alloy to which ceramics are baked. Regarding alloys.
背景の技術 歯の補綴に対して、部分的にはかなシの量で貴金属を含む合金を用いることは公 知である。Background technology The use of alloys containing precious metals in partially ephemeral amounts for dental prosthetics is not publicly accepted. It is knowledge.
詳細な説明 本発明はそのような合金における貴金属の含量を低下させることである。detailed description The present invention is to reduce the content of noble metals in such alloys.
これは貴金属の含量を著るしく減少させることができるということを明示する請 求の範囲による合金によって達成される。This is a request to specify that the content of precious metals can be significantly reduced. This can be achieved by alloying according to the desired range.
本発明は次の組成を重量％で有する例によって説明されるニクロム：２ａ７チ マンガン：ｚＯチ コバルト：５７．４チ 珪素：Ｌ４チ タングステン二８．２チ ニオビウム：１．（１ タンタル：ＬＯチ イリジウム：２１チ ジルコニウム二〇、１チ セリウム：α１チ この合金はキャスト法によシ歯の補綴のための部分を製造するのに適当である。The invention is illustrated by an example having the following composition in weight percent: Nichrome: 2a7 Manganese: zOchi Cobalt: 57.4ch Silicon: L4chi Tungsten II 8.2 inches Niobium: 1. (1 Tantalum: LOchi Iridium: 21ch Zirconium 20.1ch Cerium: α1chi This alloy is suitable for producing parts for dental prostheses by casting.
これは非常に耐腐食性であシ、従って身体と特に適合する。It is highly corrosion resistant and is therefore particularly compatible with the body.
この腐食の挙動はこの合金の次の測定結果によっても支持される：腐食媒体：空 気と接触する２３℃の水に溶解させた塩化す） ＩＪウム１チ及び酢酸１％；ｐ Ｈ値＝２．８゜ 合金の平衡残余 （ｒｇａｔ）電位”、 Ｅｘ ＝＋ ４４０ 介Ｖ合金の点食 （ｐｉｔｔｉｎｇ）電位、” Ｅ ｒ、 ＝＋ Ｉ Ｑ ２０ ｒｎ Ｆ（上記 のすべての電位値は水素標準電極に基づく）。This corrosion behavior is also supported by the following measurements of this alloy: Corrosion medium: air 1% IJ chloride dissolved in water at 23°C in contact with air and 1% acetic acid; p H value = 2.8° Equilibrium residual of alloy (rgat) potential”, Ex = + 440 Pitting of inter-V alloy (pitting) potential, “E r, = + I Q 20 rn F (above All potential values are based on hydrogen standard electrode).
本合金は微細な注造物を製造するのに適しておシ、従って７ライースクリーン・ ワイヤ（ｆｌｙ−ｓｅｒｍｏｎ ｗｉｒｅ ）に類似の構造体をキャストするこ とができる。このワイヤの厚さは同時に完全に満された容量を有してα１ｍであ ってよい。This alloy is suitable for producing fine castings and therefore Casting a structure similar to a wire (fly-sermon wire) I can do it. The thickness of this wire is α1 m with a completely filled capacity at the same time. That's fine.
本合金は１３６０’〜１３８０’の狭い且つ低い固化間隔を有する。This alloy has a narrow and low consolidation interval of 1360' to 1380'.
それ故にそれは装置及び釜の材料の双方に対する摩損作用を最小にしつつ簡単な 加熱装置を用いることによってキャストすることができる。狭い固化間隔により 、偏析現象が最小となる。合金には歯用の磁器（表面）が焼付けられる。この磁 器は層状で適用さね、耐性を有して且つしっかりと付着する。磁器と合金間の結 合はしつかりしている。磁器と合金間の接着は合金から生成する中間体酸化物に よって生じせしめられる。接着は非常に強くて、合金−磁器部分を焼付け（ｂａ ｋｉ？ｔｇ ）温度から室温まで急冷した時小片の落ちることがない。合金−磁 器部分がその先端及び端において２０ｇｍ１−’ のブロー（ｂｌｏｗｓ）の衝 撃ストレスを受けた時、磁器コーティングはその小片が合金部分から離れ落ちな い。It is therefore easy to use while minimizing the abrasive effects on both the equipment and the pot material. It can be cast by using a heating device. Due to the narrow solidification interval , the segregation phenomenon is minimized. The tooth porcelain (surface) is baked onto the alloy. this magnet The container is applied in layers and is resistant and adheres well. Connection between porcelain and alloy If it is, it is disciplined. The bond between porcelain and alloy is created by the intermediate oxide produced from the alloy. Therefore, it is caused. The bond is very strong and the alloy-porcelain part is baked (ba Ki? tg) Small pieces do not fall when rapidly cooled from temperature to room temperature. Alloy-magnetic The vessel part is exposed to blows of 20 gm1-' at its tip and end. When subjected to shock stress, the porcelain coating prevents the small pieces from falling off the alloy part. stomach.
磁器は層状にコーティングでき、９５０℃までの温度で焼結しうる。Porcelain can be coated in layers and sintered at temperatures up to 950°C.
合金からなる部分の表面には孔のない薄くて均一な酸化物層が形成され、従って 高温−腐食攻撃が合金を変えない。特に該物質は脆くなら危くて、細いワイヤ又 は細かいパネル部分がキャストできる。A thin, uniform oxide layer without pores is formed on the surface of the part made of the alloy, thus High temperature-corrosion attack does not change the alloy. Especially if the material is brittle, it can be dangerous and can cast detailed panel parts.
