本発明は、NiTl系合金からなる芯材に、被膜材料を
被覆することによって、伸線加工性及びコイリング性を
著しく向上させるNiTi系合金材料に関する。Detailed Description of the Invention 3. Detailed Description of the Invention [Field of Industrial Application] The present invention improves wire drawability and coiling property by coating a core material made of a NiTl alloy with a coating material. This invention relates to a NiTi-based alloy material that is significantly improved.
近年、NiとTiとからなるN I T i合金は、形
状記憶性能や超弾性性能、防振性能等を具えるため、そ
の実用化の為に種々研究開発が行なわれている。In recent years, various research and development efforts have been conducted to put N I Ti alloys made of Ni and Ti into practical use because they have shape memory performance, superelasticity, vibration damping performance, and the like.
しかし一般にこのようなNiTi合金の加工性は非常に
悪く、例えば、伸線加工では線引きダイスとの焼き付き
現象等によりダイス寿命を減じるとともに、断線の発生
も多くなるなど伸線性に劣る。従って、ダイス1枚当り
の加工率を低く設定せざるを得ないなどの問題点があり
、生産コストを上昇させる一部となっていた。However, in general, the workability of such NiTi alloys is very poor. For example, during wire drawing, the life of the die is shortened due to the phenomenon of seizure with the wire drawing die, and wire breakage occurs frequently, resulting in poor wire drawability. Therefore, there are problems in that the processing rate per die has to be set low, which is a part of increasing production costs.
特に従来でのNiTi合金の製造は、そのほとんどをN
iとTiとを溶解させて得た鋳塊に、多数回の熱処理と
減径加工とをくり返し行なうことにより得ることから、
熱処理間の加工率をいかに大きくとるかは非常に重要な
問題である。In particular, in the conventional production of NiTi alloys, most of the N
Since it is obtained by repeatedly performing heat treatment and diameter reduction processing on an ingot obtained by melting i and Ti,
How to increase the processing rate during heat treatment is a very important issue.
又該合金の最終用途として、例えば、バネなどに加工す
ることが多いが、この場合においても、該合金のコイリ
ング加工性が悪く、工具摩耗を橿力低くおさえるための
新たな工夫が要求されていた。In addition, the alloy is often processed into springs, etc., but even in this case, the alloy has poor coiling processability, and new measures are required to suppress tool wear to a low rolling force. Ta.
このような問題点の一端を解決するものとして、例えば
特開昭$60−9865号公報には、その表面に酸化被
膜を形成し、この酸化被膜を潤滑用被膜として利用する
ことを提案している。To solve some of these problems, for example, Japanese Patent Application Laid-Open No. 60-9865 proposes forming an oxide film on the surface and using this oxide film as a lubricating film. There is.
しかしながらこの酸化被膜は、一般的に微粒子状の硬質
な物質であるため種々加工時においては、相対的に軟質
な母材表面層に緻密かつ強固に密着し、また場合によっ
てはその内部にも食い込むという問題点があるとともに
、このような酸化被膜は、むしろダイス摩耗を助長させ
るという欠点もある。特にこのような現象は、前記加工
の程度によって変化し、高加工あるいは、多数回の減径
加工(例えば伸線加工)を行なうにつれて、前記食い込
みを助長するようである。However, since this oxide film is generally a hard substance in the form of fine particles, during various processing, it tightly and firmly adheres to the relatively soft surface layer of the base material, and in some cases, it also bites into the inside of the base material. In addition to this problem, such an oxide film also has the disadvantage of actually accelerating die wear. Particularly, such a phenomenon changes depending on the degree of the processing, and seems to increase as the processing is performed to a high degree or the diameter is reduced many times (for example, wire drawing).
また酸化被膜は黒色を呈しているため、見映えを減じ、
商品価値を低下させる。従って、用途によっではこの酸
化被膜を除去する必要があるものの、前記の如く、母材
に強固に食い込んだものまで均一かつ完全に除去するこ
とは非常に困難を伴う。In addition, since the oxide film has a black color, it reduces the appearance.
Decrease product value. Therefore, depending on the application, it is necessary to remove this oxide film, but as mentioned above, it is extremely difficult to uniformly and completely remove even the oxide film that has penetrated firmly into the base material.
従来では、前記酸化被膜除去処理のために、フン硝酸液
あるいは電解酸洗いなどが行なわれてはいるものの、こ
の場合ややもすれば、過剰脱液膜処理となって母材自体
をも溶解し、線径のバラツキ増大、あるいは表面性状の
低下等の新たな問題を生み、又その処理時に水素を吸蔵
し、その結果、水素脆性を起こすということも懸念され
る。Conventionally, nitric acid solution or electrolytic pickling has been used to remove the oxide film, but in this case, if too much liquid is removed, the base material itself will be dissolved and the wire diameter will be reduced. There is also concern that new problems such as increased variation in surface properties or deterioration of surface properties may occur, and that hydrogen may be occluded during processing, resulting in hydrogen embrittlement.
また他の比較的容易な方法としては、例えば、母材表面
に金属や有機物質を被膜することも考えられるものの、
該N i T i合金は、その内部に多量のTi元素を
含むことから、単なる被膜のみではその密着性に劣るた
め、未だこのような製品は実現されていない。Another relatively easy method, for example, is to coat the surface of the base material with a metal or organic substance.
Since the N i Ti alloy contains a large amount of Ti element therein, a mere coating alone has poor adhesion, so such a product has not yet been realized.
本発明は芯材の密着性を高めその加工性を大きく向上さ
せるとともに、最終製品での商品価値を高めるNiTi
合金材料の提供を目的とする。The present invention improves the adhesion of the core material, greatly improves its processability, and improves the commercial value of the final product.

施するのが好ましい。Substitution with such elements is effective for improving the transformation point of the core material 2 (NiTi-based alloy) itself, as well as other properties such as mechanical properties, corrosion resistance, and workability. It is preferable to implement the element in a range of 5 at% or less of the entire core material 2.

方法など種々な方法により製造したN i T i系合
金が利用できる。Within this range, the various functions such as the shape memory performance and superelasticity that the NiTi phase originally has are not affected, and as a NiTi alloy with such a composition, for example, conventionally produced melting In addition to enclosing a large number of wires made of a combination of Ti wires and Ni materials with an exterior material, the inside of the N fibers obtained by the powder alloy method and powder alloy method is of Ti
N i Ti -based alloys can be used that are manufactured by various methods, such as a method in which N and Ni are interdiffused to form a uniform N1Tt phase alloy.
特に、前述の相互拡散を利用する方法によれば、前記外

Since a large number of fine grooves 4 are formed extending toward the end, the present invention is extremely effective.

Since the coating is performed by baking a resin paint at a temperature of 0.degree. C. or higher or by coating with the coating material 3 made of a soft metal material, it has sufficient adhesion compared to ordinary coating methods.

A resin paint such as borosiloxane resin is baked onto the surface of the core material 2, or a metal material such as p' e SCu % N 1-monel alloy is applied by thermal spraying, vapor deposition, plating,
Alternatively, it can be coated by a cladding method. In particular, when using the latter metal material, prior to normal heavy processing after the coating, light processing is performed in advance at a processing rate of about 20% or less to ensure sufficient adhesion to the core material 2. Furthermore, since the metal material is soft, highly ductile, and has low work hardenability, its workability is sufficiently maintained.
又このような金属材料は、最終製品に成形した後、必要
に応じて、例えば、化学的に除去することもできる。Moreover, such a metal material can be removed, for example, chemically, if necessary after being formed into a final product.
一方前者の樹脂塗料を焼き付ける方法においても、前記

Although Ti-based alloy materials can be obtained, the inventor of the present application
Furthermore, we focused on the surface condition of the core material 2 and attempted to further improve it through various experiments. As a result, on the surface of the core material 2,
A plurality of fine A4-- extending from one end to the other end.
It was confirmed that the formation of the coating material 3 increases the adhesion retention force with the coating material 3, and as a result, it is extremely effective in improving the lubricity. As seen in FIG. 2, the fine grooves 4 are formed substantially only in the longitudinal direction, and this directionality is also the same as the running direction of the material during processing. Even in severe processing involving bending, troubles such as cracking and peeling of the coating material 3 can be prevented.

The enlarged view shown in FIG. 3 illustrates the cross-sectional state of a core material 2 having fine grooves 4 coated with the resin coating material 3. According to the figure, the surface of the core material 2, which has complex irregularities, is uniformly covered with the coating material 3, and the coating material 3 completely penetrates into the depths of the fine grooves 4. It can be seen that it is closely attached to Note that the core material 2
By the primary forming, for example, wires with circular cross sections, rods, various other shapes (cross sections: triangular, square), plate materials, pipe materials, etc. can be freely formed, and the coating material 3 is also sufficient. Since it has thermal properties and lubricating properties, it is possible to perform a superheating treatment to obtain a predetermined function (for example, shape memory performance) while it is in a coated state.
